typing: add a type hint to `mercurial/hg.py`

Somewhere between hg 3dbc7b1ecaba and hg 8e3f6b5bf720, the first value of the
tuple changed from bytes to str.  Let's lock this in, so that pytype flags it
if someone mistakenly adds a tuple with bytes somewhere.

fn main() {
    cc::Build::new()
        .warnings(true)
        .file("src/sendfds.c")
        .file("src/sighandlers.c")
        .compile("procutil");
}
