Create user "fsgqa2" and, since xfstests-dev's README uses option "-m"
while creating user "fsgqa", do the same in our codebase.
Creating user "fsgqa2" is optional along with other users according to
xfstests-dev's README. Create all these users is a preventive step since
tests needing user/users maybe skipped during execution.
