BUILD(cmake): Silence pkg-config warnings
If the systemd module was not installed (or could not be located by
pkg-config for other reasons), a big chunk of text would be emitted to
stdout stating that no such module could be found and how one might
resolve this issue. However, we don't want to throw this at our users as
we have backup code paths implemented for the case in which pkg-config
can't query the necessary information.
This commit makes sure that these warnings are not emitted anymore.
