Fix XBMC init.d script

Init.d scripts are not intended to run in a never ending loop. Among
other problems it disables the ability to log on the serial console.
Now the XBMC init.d script launches a background subshell and do necessary
things there.

xbmc-pre and xbmc-post scripts were included there too.

Conflicts:

Use standard login with getty (generic serial)
