useradd-staticids.bbclass: Read passwd/group files before parsing
Read and merge the passwd/group files before parsing the user and
group definitions. This means they will only be read once per
recipe. This solves a problem where if a user was definied in multiple
files, it could generate group definitions for groups that should not
be created. E.g., if the first passwd file read defines a user as:
foobar::1234::::
and the second passwd file defines it as:
foobar:::nogroup:The foobar user:/:/bin/sh
then a foobar group would be created even if the user will use the
nogroup as its primary group.
