RFR: 8314186: runtime/8176717/TestInheritFD.java failed with "Log file was leaked"

[Johan Sjölen]

Hi,

This PR intends to make the test a bit more sturdy by looking for both the success string and the failure string, reporting that the test messed up if neither are found. I also removed the extra newline at the end of the file and did some special reporting in case of a `TimeoutException`.

Thanks!
