merge: expand environment variables and ~/ in tool.executable

hgrc(5) already implies that this works, so we might as well support it.

Another approach would be to implement this in util.findexe(): that
would benefit other callers of findexe(), e.g. convert and anyone
calling the user's editor. But findexe() is really implemented in
both posix.py and windows.py, so this would make both of those modules
depend on util.py: not good. So keep it narrow and only for merge
tools.
