Add a file_exec_file_name RPC

* hurd/fs.defs (file_exec): Deprecate in favor of...
(file_exec_paths): ...this new RPC.
* TODO: Update.
* doc/hurd.texi: Update RPC name.
* hurd/hurd_types.h: Update RPC name.
* libdiskfs/boot-start.c: Update RPC name.
* configure.ac: Check for presence of RPC stubs file_exec_paths exec_exec_paths.
* exec/hashexec.c (check_hashbang): When file_exec_paths is available, use it
instead of file_exec.
* startup/startup.c (run, run_for_real, start_child): Likewise.
* utils/login.c (main): Likewise.
* libfshelp/start-translator-long.c (fshelp_start_translator_long): Likewise.
* libdiskfs/file-exec.c (diskfs_S_file_exec): Move code to
new function diskfs_S_file_exec_paths and call it.
(diskfs_S_file_exec_paths): New function, use exec_exec_paths when available
instead of exec_exec
* libnetfs/file-exec.c (netfs_S_file_exec, netfs_S_file_exec_paths): Likewise.
* trans/fakeroot.c (netfs_S_file_exec, netfs_S_file_exec_paths): Likewise.
* libtrivfs/file-exec.c (trivfs_S_file_exec_paths): New function.
