minijail0: adjust how we stop processing non-opts
Commit f65c9fed1a54659d309775b5eeee6800569b0547 ([minijail] stop parsing
at first non-opt arg) worked by hand checking each argument itself to see
if it started with a dash. The initial shortcircuit logic though ends up
breaking default init code that is at the end of parse_args like how we
default to forwarding signals.
Let's delete the hand parsing logic and let getopt do this for us. It has
a mode already when the optstring starts with a "+".
BUG=chromium:730682
TEST=`./minijail0 ./a.out` forwards signals
TEST=`./minijail0 -z /bin/ls --help` triggers ls's help output
