system: hurd: Remove qemu networking from %base-services/hurd.

This allows us to use %base-services/hurd for services in a Hurd config for a
real machine without removing static-networking.

* gnu/system/hurd.scm (%base-services/hurd): Factor networking out to...
(%base-services+qemu-networking/hurd): ..this new variable.
* gnu/system/examples/bare-hurd.tmpl (%hurd-os): Use it.
* gnu/services/virtualization.scm (%hurd-vm-operating-system): Use it.
* gnu/system/images/hurd.scm (hurd-barebones-os): Use it.  Add comment about
QEMU and networking for a real machine.
