hgweb: add option to convert encoding of graphdata()

Because future patches will change "|json" filter to handle input bytes
transparently, i.e. use UTF-8b encoding, "{jsdata}" must keep data in UTF-8
bytes, whereas "{nodes}" are text.

This patch inserts encodestr() where localstr is likely to survive.
