This is needed for the test f2fs/002, which tests f2fs compression in combination with encryption.

Thanks, applied. I ammended this patch to also add the lz4 package to gce-xfstests-bld.sh.

I suppose at some point we should we refactor out the package lists in xfstests-packages and gce-xfstests-bld.sh; this would require making gce-xfstests-bld.sh a generated file, however.
