Fix the msgfmt.pl script to deal with messages with plurals whose strings

are identical (e.g., msgid == msgid_plural) by ignoring the duplicates.
In fact, this is a rewrite of the script, since I couldn't understand the
old one (ew).

Also change the way we use it to only pull it in the build if the real
msgfmt does not support plurals (i.e., it's older than 0.10.36).

Fixes PR pkg/30596 and PR pkg/30938 (both related to epiphany).
It also fixes the build of evolution-data-server and probably others.
