Double-fork for xwayland execution

Browse source 
The intermediate fork needs to wait for SIGUSR1 for when Xserver is
ready, or SIGCHLD if the exec didn't work out.

Also change the exit() to _exit() as that is apparently more appropriate
for forks (and waitpid's status was wrong without it for some reason)

Fixes #122.
