linux-user: Add proper error messages for bad options

This patch adds better support for diagnosing option
parser errors.  The previous implementation just printed
the usage text and exited when a bad option or argument
was found.  This made it very difficult to determine why
the usage was being displayed and it was doubly confusing
for cases like '--help' (it wasn't clear that --help was
actually an error).
