services: Export 'service-extension' procedures.
* gnu/services.scm: Export service-extension-target and service-extension-compute. This allows for greater extensiblity of services by enabling service extensions to be wrapped. For example, the parameters passed to the compute function can be modified, or the return value of the compute function can be modified. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
