receive-pack: use default version 0 for proc-receive

Browse Source 
In the verison negotiation phase between "receive-pack" and
"proc-receive", "proc-receive" can send an empty flush-pkt to end the
negotiation and use default version 0. Capabilities (such as
"push-options") are not supported in version 0.
