Make systemd service file handling identical to tinc 1.1.

This removes hardcoded paths from systemd unit files, and sets the default
systemd unit path to ${libdir}/systemd/system. The configure option is now
renamed to --with-systemd[=PATH]. These changes now also ensure that
make distcheck runs without any errors.

Closes #160 on GitHub.
