asm-generic: add generic seccomp.h for secure computing mode 1 Those values (__NR_seccomp_*) are used solely in secure_computing() to identify mode 1 system calls. If compat system calls have different syscall numbers, asm/seccomp.h may override them.

seccomp: allow COMPAT sigreturn overrides Most architectures don't need to do much special for the strict-mode seccomp syscall entries. Remove the redundant headers and reduce the others. This patch (of 8): Some architectures may need to override the compat sigreturn definition, as is already possible in the non-compat case.
