[PATCH xserver 1/5] xwayland: Allow "-eglstream" option

The command line option "-eglstream" used to enable EGLi stream support
for NVidia GPU was made available only when Xwayland was built with EGL
stream support enabled.
Wayland compositors who spawn Xwayland have no easy way to tell whether
or not Xwayland was built with EGL stream support enabled, and adding
"-eglstream" command line option to Xwayland when it wasn't built with
EGL support would prevent Xwayland from starting (“Unrecognized option”
error).
Make sure we support the command line option "-eglstream" regardless of
EGL stream support in Xwayland, obviously without EGL stream support
this has no effect.
