[PATCH] t0107: extract HTTP body more robustly

[John Keeping]

By introducing a strip_headers() helper function, we can avoid relying
on the number of HTTP headers generated by CGit being fixed.

This function will also be useful for performing more rigid checks on
HTML body content.

This is also useful for some test suite improvements I'm working on.
I'll send an RFC for that shortly.
