Better CI (run on faster CI hosts, incremental release builds, thin-lto)

This performs a rather quick variant of Link Time Optimization [2].
It should add negligible build time but also more optimized binaries.

Setting cargo to run incremental builds means partial build results should be cached. This is not enabled by default in release mode.

Incremental builds use 256 codegen units by default [1].
We set them to 16 (release default) again for somewhat faster code but slightly slower builds.

By default, jobs without tags only run on CI runners configured to do so [1].
Conduit can use famedly runners, which are more powerfull than gitlab's runners, but require a tag on the job to run it there.
This commit tags each job with the "docker" tag.
On the famedly/conduit repo this means faster CI.
On other gitlab.com forks the normal ci.
Selfhosted gitlab's might need to add a "docker" tag to their runner.

Return proper error in case of invalid UTF-8

See merge request famedly/conduit!110

json_body is used in places that need authentication. In
case an unknown field is set, Ruma doesn't parse the field
and so doesn't give an error on invalid UTF-8. But Conduit
has parsed and on error makes json_body None. Return an
error to the client instead of generating an internal error.

Fix: Nightly release tag name should not be a branch name

According to tulir this breaks the GitLab Matrix bot, and nightly is a better match anyway
