[PATCH v2 1/2] fix group splitting in user creation

[Felix Moessbauer <felix.moessbauer@siemens.com>]

There is a bug when converting the USER_<foo>[groups] configuration
from the bitbake format (space separated) to the format useradd
expects (comma separated). We cannot simply replace spaces with commas,
as then multiple spaces in a row would create multiple commas. Instead,
we need to split it first into the tokens and then join these tokens by
comma.
