su: add --group and --supp-group options
These options allow to specify alternative groups. The command
su(1) has to be executed by root. The implementation is based on
Fedora runuser(1) command.
For example:
# su --group=kzak --supp-group=uuidd -
# id
uid=0(root) gid=1000(kzak) groups=0(root),985(uuidd),1000(kzak)
non-root user:
$ su --group=kzak -
su: only root can specify alternative groups
