Make getRelocationSection MachO only.

Browse Source 
There are 3 types of relocations on MachO
* Scattered
* Section based
* Symbol based

On ELF and COFF relocations are symbol based.

We were in the strange situation that we abstracted over two of them. This makes
section based relocations MachO only.
