TEST-13-NSPAWN.nss-mymachines: Use negative matching switch

The test expects _not_ to find the patterns but the run_and_grep would
still print 'FAIL:' message. Use the dedicated -n option that inverts
the semantics cleaner than shell's !.

(cherry picked from commit c4b75966075e01d39556a87caa778eb63d96d6f6)
