run-tests: factor out _checkhglib() to check import path of 'mercurial'.

- rename _hgpath() to _gethgpath() and move it down next to _checkhglib()
- change _gethgpath() so it caches its result: replaces global 'hgpkg'
  that anyone can use with global '_hgpath' that is only for _gethgpath()
- no need to pass 'expecthg' to runchildren() or runtests() anymore

Also: do not change global PYTHON when doing coverage; this seems to
be unnecessary, since we create a dummy 'hg' script that handles
coverage for us, and it made things brittle.  (E.g. the rest of this
patch makes the call to _hgpath() come later, and it was broken by
enabling coverage.)
