BUG/MINOR: http-htx: Don't make http_find_header() fail if the value is empty

http_find_header() is used to find the next occurrence of a header matching on
its name. When found, the matching header is returned with the corresponding
value. This value may be empty. Unfortunatly, because of a bug, an empty value
make the function fail.

This patch must be backported to 2.1, 2.0 and 1.9.
