[PATCH RFC 2/5] ephyr: ignore "-sharevts" and "-layout seatXXXX" command-line options

[Laércio de Sousa]

Multiseat-capable display managers commonly pass command-line options
like "-sharevts" or "-layout seatXXXX" to Xorg server, but Xephyr
currently refuses to start if these options are passed to it,
which may break Xephyr-based single-GPU multiseat setups.

The simplest solution to avoid this problem is making Xephyr
ignore such options.
