hgweb: escape REMOTE_HOST when passing url for addchangegroup

If DNS lookups are turned off on the web server, REMOTE_HOST may be
populated with REMOTE_ADDR, which, if the remote is an IPv6 hosts will
contain colons, thus interfering with the separator character. This is
solved by URL quoting the REMOTE_HOST string.
