MINOR: hlua_fcn: add Patref:del()

Browse Source 
Just like "del map" and "del acl" on the cli, the Patref:del() method can
be used to delete an existing entry in the pattern reference pointed to
by the Lua Patref object. The update will target the live pattern
reference version, unless Patref:prepare() is ongoing.
