ecore-drm: Fix trapping of SIGUSR1 for VT switching signals 

SIGUSR1 is used here to catch VT switching and either acquire or
release the VT. The problem is that XWayland Also sends SIGUSR1 when
it has finished initializing. In order to not get confused about where
the SIGUSR1 came from we can check the pid inside the siginfo
structure and see if it matches.

@fix
