RFR: 8353489: Increase timeout and improve Windows compatibility in test/jdk/java/lang/ProcessBuilder/Basic.java [v2]

[Oleksii Sylichenko]

> This PR proposes three improvements to the `Basic.java` test:
> 
> 1. Increase Timeout
>    - The current timeout is insufficient when running the test in IntelliJ IDEA.
>    - I propose increasing it by one minute.
>    - The timeout value was last modified on May 13, 2010 (commit [56131863a71c](https://github.com/openjdk/jdk/commit/56131863a71ca552d0a881364bd2b3581e13f058)) and has remained unchanged since then.
> 
> 2. Fix Incompatibility with Windows (Cygwin vs. Native)
>     - One of the tests executes the `echo` command.
>     - This works in Cygwin but fails when running the test in a pure Windows environment (e.g., IntelliJ IDEA).
>     - I propose replacing echo with `cmd /c echo.`, which produces the same output (a single newline) in Windows, ensuring compatibility.
> 
> 3. Prevent Autorun Scripts in the `cmd /c set` Command
>     - The test runs `cmd /c set`, but in Windows, this may trigger autorun scripts.
>     - I propose adding the `/d` options to prevent autorun scripts from affecting the test results.
> 
> These changes improve test reliability and ensure compatibility across different environments.
> Testing:
> - Verified that the test runs successfully in IntelliJ IDEA without timeout issues.
> - Confirmed that `cmd /c echo.` produces the expected output in Windows.
> - Ensured that `cmd /d /c set` correctly lists environment variables without executing autorun scripts.
> 
> # Detailed Description
> 
> ## echo
> The following test fails in a clean Windows environment (e.g., when run from IntelliJ IDEA without Cygwin):
> 
> //----------------------------------------------------------------
> // Test Runtime.exec(...envp...) with envstrings without any `='
> //----------------------------------------------------------------
> 
> with following error:
> 
> Cannot run program "echo": CreateProcess error=2, The system cannot find the file specified
> 
> 
> If we try to run `echo` as a process in Windows, for example from IntelliJ IDEA, we get the error above, because Windows does not have such an executable, but instead this is a command of the Command Processor (CMD).
> 
> The `echo.` command with the `.` works the same way as calling `echo` without parameters in Unix — it outputs an empty line.

> See: https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/echo
> 
> To ensure that the `echo.` command is supported in Cygwin, we need to invoke it via `cmd /c`, because Cygwin has its own executable `echo`.
> 
> ## cmd.exe /c set
>  The following test fails in a Windows environment under specific conditi...
