* Implemented some basics for supplementary groups support:

Browse Source 
- The kernel stores the group IDs in the team structure. They are
    correctly inherited on fork() and load_image_etc().
  - Implemented getgroups() for real, i.e. it retrieves the groups
    associated with the process.
  - Implemented setgroups(), initgroups() and (the BSDish)
    getgrouplist(). The latter two read the group information from the
    "group database" /etc/group (if existing).
  - Change the BIND port config, since we do have getgrouplist() now.
* The set-uid feature was broken when the path to the executable was
  relative, since we used stat(), which, in the kernel, uses the kernel
  IO context.
