datapath: Allow minimum headroom to be set when copying buffers.

If we need to copy an sk_buff in order to make it writable, allow
the minimum headroom to be specified.  This ensures that if we
need to add additional data, such as a VLAN tag, we will not have
to make a second copy.

Solves bug #2197 in certain situations.
