hfsprogs: initial import

Adds supports for hfsprogs, allowing the creation and verification of
HFS/HFS+ filesystems.

This creates two selectable packages:
- hfsfsck
- mkhfs

A filesystem checking script is included with hfsfsck to allow OpenWrt
to check/repair filesystem errors.

Using Ubuntu's 332.25 sources plus their patches from debian/patches/.
