[Buildroot] [git commit branch/2020.05.x] package/{collectd, domoticz}: fix outdated dependencies for mosquitto

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=c4618cdb80b332efe67c33a4cd0a95600056ee1d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.05.x

In 4fc62e1eb6b3adbfc3d3eb7f841275ae8cd1b424, we removed arch/toolchain
dependencies from the mosquitto library (MMU, !STATIC, SYNC4), and moved
them to the mosquitto broker only.

All the packages modified here only need the mosquitto library, so they
shouldn't have those depends anymore; but this was never done before.
