policycoreutils: fixfiles: if restorecon aborts, we should too

New users may try something like `fixfiles restore -v /dir/file` -
not realizing they are required to use `fixfiles -v restore /dir/file`.

Detect that `restorecon` aborts due to being run on the non-existent file
`-v`, and stop immediately.  This will show the error much more clearly,
instead of continuing to restore `/dir/file` *without* verbose messages.
