Fixed socket usage to work with AFS home folders.

On corporate/university environments it is not uncommon for the home
folder of each user to be hosted on OpenAFS (so you can work from any
terminal and IT services can backup everything at will).

However it is not possible to create sockets in AFS, hence when awesome
attempts to create a socket at ~/.awesome-ctl it fails. To fix this
awesome now uses /tmp/.awesome-ctl as a fallback before giving up.
