weston: Add support for "--foo bar" style options

A little earlier today I ended up spending a lot of time trying to
figure out why weston wasn't managing to launch over SSH and telling me
that I did not have a --tty option specified, despite me passing the
option strings ["--tty", "3"]. Turns out weston just doesn't support
that.

So, add support for this kind of format in addition to "--foo=bar" to
save others from making the same mistake I did.

Changes since v1:
 - Add comment about unreachable boolean check in long_option_with_arg()
 - Convert boolean check in long_option_with_arg() to assert
