seccomp: Document RESTART_BEFORE_RECV and O_PATH addfd
Describe SECCOMP_FILTER_FLAG_RESTART_BEFORE_RECV in the UAPI header, as
SECCOMP_FILTER_FLAG_WAIT_KILLABLE_RECV is described above it, and say in
the documentation that supervisors must tolerate ENOENT from
SECCOMP_IOCTL_NOTIF_RECV, which the flag makes routine. Note at the
fget_raw() call that O_PATH files are allowed on purpose.
Build tested ARCH=x86_64 defconfig (kernel/seccomp.o and headers) with
GCC 16.2.0, and SPHINXDIRS=userspace-api htmldocs.
