Fixed namespace pollution related to `err' in libc in the same way as for

`warn'.  Now a whole 2 members of the err() family don't cause pollution.

This fixes world breakage in awk for NOSHARED worlds. contrib/awk/msg.c
has had its own version of err() for a long time, but this somehow
didn't cause problems until the update to awk-3.1.0.
