elf/x86-64: Adjust relocation for PE/x86-64 inputs

PE linker calls _bfd_relocate_contents to resolve relocation, instead of
bfd_perform_relocation.  But ELF linker calls bfd_perform_relocation, not
_bfd_relocate_contents.  When linking PE/x86-64 inputs to generate ELF
output, we need to adjust PE/x86-64 relocations in bfd_perform_relocation.

Enable PE/x86-64 in bfd together with PEI/x86-64.  Update run_ld_link_tests
to handle bzip2 binary inputs.

bfd/

	PR ld/26583
	* config.bfd (targ64_selvecs, targ_selvecs): Add x86_64_pe_vec
	to x86_64_pei_vec.
	* reloc.c: Include "coff/internal.h".
	(bfd_perform_relocation): Adjust relocation for PE/x86-64 inputs.
