[PATCH] kvm-xfstests, gce-xfstests: correct file permissions with --update-files

[Eric Biggers <ebiggers@google.com>]

The xfstests-bld repository may have been cloned with a umask that
masked out the other bits.  When using --update-files in this situation,
the VM ended up in a state where non-root users were unable to execute
anything, which made all tests using the fsgqa user get skipped.  Fix
this by copying the r and x group bits to the other bits when creating
files.tar.gz.  Also set the owner and group to root while we're at it.
