subrepo: add missing arg to dirty()

Upstream Mercurial has added a new 'missing' argument to the dirty function. We
need to add it as well. The default argument should mean this is backwards
compatible with older Mercurials.

I don't understand the subrepo or hgsubverison code 100%, so this patch is my
best attempt at a fix.
