This adds support to the ELF to PE/COFF conversion performed by GenFw for
the AArch64 ELF relocation types R_AARCH64_PREL64, R_AARCH64_PREL32 and
R_AARCH64_PREL16. Since we already require the ELF and PE/COFF section
layouts to be identical in order to support other relative relocation
types, this is simply a matter of whitelisting these new relocation types
in the same way.
While we're at it, clean up the code a bit, and add a comment explaining
why these relocations are ignored in WriteRelocations64 ().
