useradd-staticids.bbclass: Do not require trailing colons
Before, the users and groups specified in the passwd file and the
groups file had to have trailing colons to make sure there were enough
elements in the definitions, or bitbake would throw a Python
exception. After this change one can omit the trailing colons, which
especially simplifies passwd files used only to specify static UIDs.
