man-pages: fix links to moved manpages
The template file renames `rand.3` and `err.3` to `glibc-rand.3` and `glibc-err.3` to resolve conflict with openssl manpages, but it doesn't fix manpages linking to the old version. These manpages (`warnx(3)`, `srand(3)` ...) then won't know where the manpages are. This PR redirects them to the renamed version.

Subject: [PATCH] man-pages: fix links to moved manpages

The template file renames rand.3 and err.3 to glibc-rand.3 and
glibc-err.3 to resolve conflict with openssl manpages, but it
doesn't fix manpages linking to the old version. These manpages then
won't know where the manpages are. This commit redirects them to the
renamed version.
