getgroups: fix logic error

The replacement getgroups mistakenly failed with EINVAL if there
were more than 20 groups, since -1 < n_groups.  Also, realloc
geometrically rather than linearly.

* lib/getgroups.c (rpl_getgroups): Don't fail if current process
has more than 20 groups.
* modules/getgroups-tests: New test.
* tests/test-getgroups.c: New file.
