Record executable entry for PIE core dumps
* hurd/process.defs (proc_set_entry, proc_get_entry): New RPCs.
* hurd/process_reply.defs: Add skips for proc_set_entry, proc_get_entry.
* hurd/process_request.defs: Likewise.
* exec/exec.c (do_exec): Call proc_set_entry.
* proc/proc.h (proc): Add p_entry field.
* proc/mgt.c (S_proc_set_entry, S_proc_get_entry): New RPC
implementations.
* exec/elfcore.c (dump_core): Add at_entry note, call proc_get_entry to
get it, and write it with WRITE_NOTE.
