fai-cd: quotes around command for -x test

[michael log]

Hello,

There should be quotes around the $(command) for the -x test shell
builtin: [ -x "$(command)" ]
This is owing to the following:

debian:~# which rsync
/usr/bin/rsync
debian:~# which rsync_x
debian:~# [ -x "$(which rsync)" ] && echo ok
ok
debian:~# [ -x "$(which rsync_x)" ] && echo ok
debian:~# [ -x $(which rsync) ] && echo ok
ok
debian:~# [ -x $(which rsync_x) ] && echo ok
ok
debian:~#
