sys-process/rtirq: version bump to 20180209

- Install systemd service file.
- Bump to EAPI 7.
- Drop explicit RDEPEND on sys-apps/util-linux.
- Group variables as in skel.ebuild.
- Update LICENSE to GPL-2+ in accordance with rtirq.sh.
- Do not use PN variable in src_install.
- Remove OpenRC specific code that was not very useful anyway.
- Use KV_LOCAL from linux-info to detect if the current kernel is
  realtime or not.
- Avoid using grep unnecessarily.
