rhg: more efficient `HgPath::join`

This commit makes `HgPath::join` slightly more efficient
by avoiding one copy.

It also avoids a particularly inefficient (quadratic) use of
`HgPath::join` by using a new mutating function `HgPathBuf::push` instead.

The name for `HgPathBuf::push` is chosen by analogy to `PathBuf::push`.
