[llvm-objcopy] Add AMDGPU case to binary-output-target.test

Add test coverage for converting binary input to elf64-amdgpu format,
verifying the output has the correct format string, arch (amdgpu),
and machine type (EM_AMDGPU 0xE0). Follows the same pattern as all
other architectures in this test file.

[llvm-objcopy] Fix AMDGPU arch checks in tests

ELFObjectFile.h getArch() for EM_AMDGPU returns Triple::UnknownArch
when e_flags & EF_AMDGPU_MACH is 0 (no GPU target specified). Only
when a MACH flag in the AMDGCN range is present does it return
Triple::amdgpu.

- cross-arch-headers.test: restore EF_AMDGPU_MACH_AMDGCN_GFX900 flag
  on the input ELF so that after format conversion the output correctly
  reports Arch: amdgpu.

- binary-output-target.test: expect Arch: unknown since converting
  from raw binary input (-I binary) produces an ELF with e_flags=0
  (no MACH flags), giving UnknownArch. This is correct behavior.
