build: Fix systemd --config option

The --config command line parameter in the systemd service unit was
never properly set at install, because the CMake variables
LIBTOML_LIBRARIES and DISABLE_CONFIGFILE are only defined after
descending into the `src/` directory. The systemd service file is
correctly configured if CMake does this *after* it processed
`src/irmd/CMakeLists.txt`.

There should also be a path seperator in between the config directory
and the config file, which wasn't the case anymore due to
e35302ca0ab64edd21b9d8e40d3aa74a3a4f4f7e.

Refine the config file wording at the same moment.
