empathy: remove package.
https://github.com/void-linux/void-packages/pull/28963

Description:
Has been abandonware for at least three years, as seen in [1].
This is not great for a network exposed messenger, though it hasn't
received any CVEs as far as I could find.

It is also a blocker for enchant 1.x removal, though this is easy to fix
with the patch from [2]. I decided not to go with this option for the
reason listed above.
