Alien ruleset: Change specialist name to avoid savegame corruption

The name of the "Government Merchants" specialist contains a space. The
specialist rule name is used as an entry name in savegames. Freeciv savegames
are section files. Section file entry names can't contain spaces.

Add a separate rule name without a space to make saving work again.
