Do not use extra command options in the automount plugin

Allowing Commands to be called with ignored unknown options opens the
door to problems, for example with misspelled option names.
Before we start rejecting them, we need to make sure IPA itself does
not use them when it calls commands internally.

This patch does that for the automount plugin and its tests.
