[Bug-wget] [Patch] fix bug #39175 Header value length limited with 256

[Miquel Llobet]

Increased the header buffer to 8Kb, as there are no limits to the size of
field name, values or headers themselves. While the current value is big
enough, other projects such as Apache [1] or nginx have limits of 4-8Kb.

If we want to allow for arbitrary size headers we should use
resp_header_strdup instead of resp_header_copy, but this new value should
be enough.
