[PATCH] tests: avoid false failures with default ACLs

[Pádraig Brady]

To reproduce:
  setfacl -dm group::rx .
  setfacl -dm other::rx .
  make check

* init.cfg (require_no_default_acl_): A new function to skip
when default ACLs are detected, or if the getfacl utility is
not available then skip if any non LSM ACLs detected.
* tests/cp/existing-perm-race.sh: Call require_no_default_acl_.
* tests/mkdir/parents.sh: Likewise.
* tests/mkdir/perm.sh: Likewise.
