* Query systemd for unit file paths on install/uninstall. This makes our installation code more portable and more concise, and should make the uninstallation code significantly more robust. Also includes a number of other improvements to systemd handling and updater handling in the uninstaller that should make it much more thorough and reliable. * Fix issues brought up in code review, and better support old systemd versions. * Replace sed with AWK for readability. * Fix uninstaller loop. * Fix unit file detection in updater code.
