Subject: ash: reject unknown long options

Commit 64f70cc755 (Add --login support) added code in options()
to handle the bash-compatible '--login' option.  In doing so it
committed BusyBox ash to silently accepting all other long
options.

Restore compatibility with other ash variants by rejecting unknown
long options.

(GitHub issue #457)
