Fixes bug #21226.

Linux 3.19 introduced a fix for a security vulnerability in user namespaces.
This fix introduced a new proc file called 'setgroups' and was backported to
many older kernels.  However, some users run a kernel that is new enough to
support user namespaces yet old enough to not include the patch, so we must
skip the tests.

* tests/containers.scm: Skip all tests if /proc/self/setgroups does not exist.

It's not always possible to map 65536 uids when creating a container as the
root user within another user namespace.  This is true when building Guix
within the build daemon's container.  By using a uid range of 1 by default,
even as the root user, the tests now pass.

* gnu/build/linux-container.scm (initialize-user-namespace, run-container):
  Add 'host-uids' argument.
  (call-with-container): Add #:host-uids keyword argument.
