py3: make check-py3-compat.py use correct module name at loading pure modules

Before this patch, check-py3-compat.py implies unintentional ".pure"
sub-package name at loading pure modules, because module name is
composed by just replacing "/" in the path to actual ".py" file by
".".

This makes pure modules belong to "mercurial.pure" package, and
prevents them from importing a module belonging to "mercurial" package
relatively by "from . import foo" or so.

This is reason why pure modules fail to import another module
relatively only at examination by check-py3-compat.py.
