[oe] [PATCH][meta-networking] ntp: control refclock driver support via PACKAGECONFIG

[Andre McCurdy]

The default configuration of ntp includes a large number of reference
clock drivers. Provide a PACKAGECONFIG to allow control over whether
or not these refclock drivers are built. Leave enabled by default.
