[OE-core] [PATCH 2/3] gitsm.py: support BB_NO_NETWORK during do_unpack

[Mikko Rapeli]

'git submodule update --init -recursive' will clone remote repositories
if local tree does not have the referenced commits. Add --no-fetch
to git submodule update if BB_NO_NETWORK is defined and only local
download caches should be used.
