systemd-systemctl: parse unit files more correctly

Old script failed to parse unit files containing comments like

| #Alias=some-alias

or whitespaces like

| WantedBy = foo

correctly.  Patch changes script to interpret keywords only when they
are at the beginning of a line and ignores whitespaces before the '='.
