xfstests-bld: fix check script argument ordering bug

The check script called by runtests.sh in the test appliance to control xfstest execution requires that all optional arguments precede any test names on its command line. Violation of this requirement results in an error message ("Arguments before tests, please!") and an immediate exit without test execution.

runtests.sh violates this requirement when it runs a specific test in a configuration that defines TEST_SET_EXCLUDE (contains -x argument).

To reproduce the bug, run "kvm-xfstests -c bigalloc generic/375".
