release: automate uploading of web manuals in CVS

This is partly inspired to the 'gnu-web-doc-update' script from
gnulib.  Unfortunately, we can't use that script directly, because
as of now it assumes a build system integrated with gnulib.

* Makefile.am (upload-web-manuals): New .PHONY rule.
(RSYNC, CVS, CVSU, CVS_USER, WEBCVS_ROOT): New variables, used by
the new rule.
