Remove unused Linux libthread_db callbacks

Browse Source 
gdb/proc-service.c includes several libthread_db callbacks that do not
exist in gdb/gdbserver/proc-service.c.  Other than in proc_service.h,
there is no reference to any of these callbacks in any revision of
nptl_db or linuxthreads_db in glibc's git repo so it seems likely that
these functions have never been called.  This commit removes them.
