Use better defaults for installation locations

These defaults assume the installation will be system wide either on
/usr or /usr/local prefix. If the user wants to separate the
installation completely from their system SYSCONFDIR, LOCALSTATEDIR,
GSAD_PID_DIR, GVM_RUN_DIR and SYSTEMD_SERVICE_DIR need to be adjusted.
