lxc-ubuntu-cloud: get full pathname to userdata file

Browse Source 
When passing '--userdata somefile' to the ubuntu-cloud template, a user
may pass a relative pathname.  The template uses the filename after
changing current directory, so store the full pathname for the userdata
file instead of a potential relative pathname.
