RFR: 8368192: Test java/lang/ProcessBuilder/Basic.java#id0 fails with Exception: Stack trace [v3]

[Roger Riggs]

> 8368192: Test java/lang/ProcessBuilder/Basic.java#id0 fails with Exception: Stack trace
> With MacOsX Sequoia 15.7 the command environment contains a new TMPDIR variable.
> The ProcessBuild/Basic test checks for a small set of variables set in the parent
> and ignores variables that are set by the OS or runtime, now including TMPDIR.
> 
> In the Basic test, for MacOSX, checks of the environment in the child should ignore TMPDIR in addition
> to the other existing environment variables that are expected.

Roger Riggs has updated the pull request incrementally with one additional commit since the last revision:

  Simplify the code to match and remove expected environment variables on MacOSX.
