RFR 9: 8135094 : (process) java/lang/ProcessHandle/InfoTest fails testing commandLine()

[Roger Riggs]

Please review this test fix.
The test assumes that the pathname of the command is literally the same as
the executable path provides to ProcessBuilder. However, if the path 
contains
a symbolic link, it is resolved and the real path is reported as the 
command.
