SYS_SECCOMP

[enh]

yeah, i mean what you get in si_code to tell you that the SIGSYS was
from seccomp.

bionic gets them for free from the uapi <asm-generic/siginfo.h>:

/*
 * SIGSYS si_codes
 */
#define SYS_SECCOMP 1 /* seccomp triggered */
#define SYS_USER_DISPATCH 2 /* syscall user dispatch triggered */
#define NSIGSYS 2

musl seems to have copy & pasted them into <signal.h>.
