hgweb: discard Content-Type header for 304 responses (issue5844)

A side-effect of 98baf8dea553 was that hgwebdir always sets a global
default for the Content-Type header. HTTP 304 responses don't allow
the Content-Type header. So a side-effect of this change was that
HTTP 304 responses served via hgwebdir resulted in a ProgrammingError
being raised.

This commit teaches our 304 response issuing code to drop the
Content-Type header.
