Remove lib-src/rcs-checkin

This script isn't used by Emacs, and I can't imagine anyone else is
using it any more either...  From the commentary:
"This script is intended to be used to convert files with an
old-Emacs-style version history for use with VC (the Emacs 19
version-control interface), which likes to use RCS as its back end."

* lib-src/rcs-checkin: Remove file.
* lib-src/Makefile.in (INSTALLABLE_SCRIPTS, STAMP_INST_SCRIPTS):
Remove rcs-checkin.
(stamp-rcs-checkin): Remove.

* INSTALL, make-dist: Remove rcs-checkin.

* admin/quick-install-emacs (PUBLIC_LIBSRC_SCRIPTS): Remove rcs-checkin.

* doc/man/rcs-checkin.1: Remove.

-# Arguments which are detectably either RCS masters (with names ending in ,v)
-# or Emacs version files  (with names of the form foo.~<number>~) are ignored.
-# For each file foo, the script looks for Emacs version files related to it.
-# These files are checked in as deltas, oldest first, so that the contents of
-# the file itself becomes the latest revision in the master.
-#
-# The first line of each file is used as its description text.  The file itself
-# is not deleted, as under VC with vc-keep-workfiles at its default of t, but
-# all the version files are.
-#
-# If an argument file is already version-controlled under RCS, any version
-# files are added to the list of deltas and deleted, and then the workfile
-# is checked in again as the latest version.  This is probably not quite
-# what was wanted, and is the main reason VC doesn't simply call this to
-# do checkins.
