build: generate man pages even when existing targets are read-only
* doc/Makefile.am (grep.1): Use mv -f to move temporary to target,
in case the target is read-only. Also, always make the generated
files read-only.
(egrep.1 fgrep.1): Likewise.
This avoids a build failure reported by Eric Blake in
http://lists.gnu.org/archive/html/bug-grep/2014-10/msg00112.html
