hgweb: assign ctype to requestcontext

The very existence of ctype is a bit hacky. But we roll with it.

Before this patch, there was possibly a race condition between 2
threads handling file requests: 1 thread could set the ctype and
another serving a different file would read and use that potentially
wrong ctype.
