[oe] [PATCH] Fix the package_arch=machine_arch logic to use FILESPATH*

[Chris Larson]

From: Chris Larson <chris_larson at mentor.com>

- Use FILESPATHPKG and FILESPATHBASE to locate the machine specific dirs
- Use the fetch urldata rather than poking at urls ourselves
- Move the logic into utils.bbclass as def'd python functions
- Simplify
