ephyr: if -parent is given, check for a trailing -screen. (#24144)

If -parent is given, don't open up a new window if -screen is given as well.
The commandline option -screen allows to set the depth of the embedded
Xephry instance, even though width and height are autoscaled on -parent.

This patch checks for a -screen parameter after -parent and - if one is
found - delays initializing the screen. The parent window id is stored
temporarily but re-set after a -screen argument.
The following command is thus valid:

Xephyr -parent 1234 -screen 640x480@8 -screen 1024x768

It embeds the first 8-bit screen into window 1234 and opens up a new window
for the second screen. Multiple parent arguments are possible, the screens
are embedded in-order.
