nghttpx: Don't rewrite path if http2 proxy or client proxy is enabled 

There are many requests which changes its meaning when we rewrite
path.  This is due to bad percent-encoding in URI; reserved characters
are just used without percent encoding.  It seems this is common in ad
services, but I suspect more to come.  For reverse proxying situation,
sane service most likely encodes URI properly, so probably this is not
an issue.
