efisecdb: do not free optarg

The *outfile passed to parse_input_files can only be either set to
optarg or be NULL. optarg should not be free'd and NULL does not need
to.

Since we no longer use on_exit to unlink outfile we also don't need to
set *outfile to NULL.

Fixes commit d917870 (efisecdb: add efisecdb)
