[RFC PATCH V3 1/2] scripts: dtc: build fdtget for extracting properties from dtbs

In order for 'make dtbs_install' to be maintainable, we need a reliable
way to determine the board compatible string for a given dtb. fdtget
does that easily as written, but currently isn't built by the kernel.

changes since v2:
- switch from modifying dtc to building fdtget
changes since v1:
- made patch against in-tree dtc code to facilitate testing
- dtc prints compatible string to stdout now, instead of creating symlink
- should be more flexible for end-users
