xfstests: 077 should require fsgqa user

Running on a newly-provisioned box:

 QA output created by 077
 *** create filesystem
 *** set default ACL
+setfacl: Option -m: Invalid argument near character 3
 *** populate filesystem, pass #1
 *** populate filesystem, pass #2
 *** all done

because we didn't have the fsgqa user, and tried:

# setfacl -R -dm u:fsgqa:rwx,g::rwx,o::r-x,m::rwx ...

instead should have had:

077	 [not run] fsgqa user not defined.
