x86: switch to using asm-generic for seccomp.h
Switch to using the newly created asm-generic/seccomp.h for the seccomp strict mode syscall definitions. The obsolete sigreturn syscall override is retained in 32-bit mode, and the ia32 syscall overrides are used in the compat case. Remaining definitions were identical.
