[PATCH] xfstests: filter out selinux xattrs for generic/062

[Josef Bacik]

If you have selinux enabled getfattr will show the selinux xattrs, which screws
with the golden output of generic/062.  To make matters worse you can't just
greap it out because we'll still get the preamble and newline from getfattr when
the selinux attr is the only attr.  So this is the voodoo I came up with after
way more time than I'm comfortable admitting to make this test pass if you have
selinux enabled.  Thanks,
