subrepo: fix path normalization

Calling posixpath.normpath() on a Windows path does not work as expected:

  >> posixpath.normpath('c:\\foo\\bar/../baz')
  >> 'baz'

Either the path should be first normalized to have a slash as separator, or
they should be handled by platform specific normalization routines.
