RFR: JDK-8247229: jpackage tests failed due to "semop(1): encountered an error: Invalid argument"

[Alexey Semenyuk]

Please review fix [2] for jpackage bug [1].

Sometimes jpackage fails building .deb package due to failure of 
`fakeroot` command with the same error message printed in stderr: 
`semop(1): encountered an error: Invalid argument`.
The suggested fix is to rerun `fakeroot` command if it fails and the 
known error message is pritnted to stederr.
