upload-pack: move static vars to upload_pack_data

As we cleanup 'upload-pack.c' by using 'struct upload_pack_data'
more thoroughly, let's move the 'no_done', 'daemon_mode' and
'timeout' variables into this struct.

They are only used by protocol v0 code since protocol v2 assumes
certain baseline capabilities, but rolling them into
upload_pack_data and just letting v2 code ignore them as it does
now is more coherent and cleaner.
