log: Set log_define properly

This sets lxc_log_define to what should be appropriate values for all
existing binaries that call lxc_log_init.

The name is lxc_<bin name>_ui for anything that's user visible and
lxc_<bin name> for anything that's not.

The parent is set to "lxc" for anything using the API and to the
matching C file name for anything that isn't.
