build: Move lcovrc file to root so it’s picked up by Meson

Move the lcovrc file to the root of the project, so that it’s picked up
by Meson when running `ninja coverage` locally.

See https://github.com/mesonbuild/meson/issues/4628

This won’t affect the code coverage run on the CI, since that explicitly
used the lcovrc file already.
