[PATCH 4/4] Use --not-so-strict on all pack transfer for connectivity check

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This replaces check_everything_connected() with --not-so-strict, which
accomplishes the same thing and is generally cheaper.

This also forces connectivity check on "git clone".
