Move EM_ARCOMPACT and EM_ARCV2 to uapi/linux/elf-em.h These should never have been defined in the arch tree to begin with, and now uapi/linux/audit.h header is going to use EM_ARCOMPACT and EM_ARCV2 in order to define AUDIT_ARCH_ARCOMPACT and AUDIT_ARCH_ARCV2 which are needed to implement syscall_get_arch() which in turn is required to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

ARC: gdbserver using regset interface possibly broken ptrace regset interface relies on ELF_NGREG for ceiling the size of user request. So any larger request (even if legit) would be clipped. The existing def of ELF_NGREG didn't use user_regs_struct and was technically one placeholder short (stop_pc) - although the current code would still work because pt_regs includes a bunch of extra fields, making ELF_NGREG >= sizeof(struct user_regs_struct)/sizeof(long) But we need to remove this ambiguity, specially since pt_regs should NOT be directly associated with with anything userspace-ish.
