Make util.find_exe alway returns existing file, fixing issue1459

It seems like the old behaviour with different handling for commands with and
without path was intended, but I think this behaviour of util.find_exe is
better:
* Always returns existing file
* or None if command not found - no default
* Windows: Returned file thus always ends with extension from PATHEXT

This fixes http://www.selenic.com/mercurial/bts/issue1459. The change might
fix other unintended behaviour too.
