RFR: 8000975: (process) Merge UNIXProcess.java.bsd & UNIXProcess.java.linux (& .solaris & .aix)

[roger riggs]

Hi Peter,

I ran into one test problem when running this through its paces.

The test: test/java/lang/ProcessBuilder/SecurityManagerClinit.java
throws a package access exception while creating a lambda
due to the wacky security manager and forbidding of access to java.util.
I hacked the test to remove the limitation on java.util.

This looks good to me but a more experienced Reviewer should look at it.

Thanks, Roger
