mod_proxy_fcgi: Fix sending of response without some HTTP headers
that might be set by filters.

The problem occurs when no body bytes were read while reading the
response headers, resulting in an empty brigade being sent down
the filter stack.  One particualr filter that mishandles the empty
initial brigade is mod_deflate.  It neglects to add to the response
header fields.

Do not perform a p+= 7 that could go past the end of the buffer in case we find a 'content' without a corresponding '='.

Should we need to deal with this case, a new search should be performed to find the real starting position of another potential 'content=' pattern.
