Jessica Clarke ef3bab610d CIrrDeviceLinux: Fix type for NET_WM_PID XChangeProperty 
This uses format=32 which in X11's API means a C type of long (with
restricted range when > 32 bits). pid_t is of unknown type, though on
Linux and FreeBSD it's a 32-bit type, so does not have the same size as
long on 64-bit architectures, and thus XChangeProperty reads outside its
bounds. Fix this by casting to and passing a long.
