hgweb: expose raw line numbers to templates

Surpringly, the templates didn't receive an unmodified version of the
line numbers. Expose it to make implementing the JSON templates easier.

In theory, we could post-process an existing template variable. But
extra string manipulation seems quite wasteful, especially on items that
could occur hundreds or even thousands of times in output.
