dns/dnsmasq-devel: update to v2.91test3.

This still needs my patches added for test2; while the public
repo as of this commit does not have the v2.91test3 tag,
I suppose it's 3ac11cd from looking at the tarball; we have
DSYNC added to src/cache.c but not the de.po update.

This makes for the upstream changes since v2.91test2 then:

• 3ac11cd 2024-12-22 | Add newly assigned RRTYPE DSYNC [DL6ER]
• 5d49fa1 2024-07-26 | Add newly assigned RRTYPEs NXNAME, CLA, and IPN [DL6ER]
• d29d19e 2024-06-21 | Add newly assigned RRTYPE WALLET (262) [DL6ER]
• 49ea7db 2024-12-23 | Fix c9bc0156a8d36d56735831cb81e786d628ed73e [Simon Kelley]
• fcb40ee 2023-10-16 | Fix dependency in make install target [Olaf Hering]
