a6ada1a50c Fix a warning related to SCMP_CMP definition in header.
SCMP_CMP(a,b,c) leaves the fourth field of the structure undefined,
giving a missing-initializer error.  All of our uses are
three-argument, so I'm overriding the default.

85178e2e93 Use format_hex_number_sigsafe to format syscalls in sandbox.c
This way, we don't have to use snprintf, which is not guaranteed to
be signal-safe.

(Technically speaking, strlen() and strlcpy() are not guaranteed to
be signal-safe by the POSIX standard. But I claim that they are on
every platform that supports libseccomp2, which is what matters
here.)

f9c1ba6493 Add a basic seccomp2 syscall filter on Linux
It's controlled by the new Sandbox argument.  Right now, it's rather
coarse-grained, it's Linux-only, and it may break some features.
