getfacl acceptance test should not fail on redhat

getfacl fails on RH because of an error message about removing leading '/' from absolute paths.
The option "--absolute-names" is meant to get rid of this message but it has no effect when supplied to the command.
This is why I am using grep to filter it and make the test succeed.

The test succeed however as a result of acl is not supported by the underlying system :(
