Replace some calls to `intern' with DEFSYMs

Browse source 
* src/filelock.c (lock_file, unlock_file_handle_error): Call
constant symbols rather than interning them all the time.
(syms_of_filelock): New symbols Qask_user_about_lock,
Quserlock__handle_unlock_error, and
Quserlock__ask_user_about_supersession_threat.
