hexchat: update to 2.16.0 and maintainer change
https://github.com/void-linux/void-packages/pull/33273

Description:
- Remove obsolete [host]makedep 'libxml2-devel' as hexchat does not use libxml2
- Add makedep 'python3-cffi'
- Add hostmakedep 'python3-cffi' for crossbuilds
- Update configure args for dbus and tls (upstream renamed them)
- Remove configure args for building the text interface (now disabled by default by upstream)
- Add configure arg for libcanbera
- Remove patch for cross compile (introduced in 32a4badf)
    The file it applies to is now unrecognisable, and the patch *seems* unneeded

- Change the maintainer from Orphan

- Remove obsolete 'update' file (project has moved to github releases)
