perf dwarf-regs: Pass accurate disassembly machine to get_dwarf_regnum
Rather than pass 0/EM_NONE, use the value computed in the disasm
struct arch. Switch the EM_NONE case to EM_HOST, rewriting EM_NONE if
it were passed to get_dwarf_regnum. Pass a flags value as
architectures like csky need the flags to determine the ABI variant.
