seccomp: Make seccomp.sh re-entrancy safe
seccomp.sh generates seccomp.h piece by piece using >> directives. This
means that if two instances of seccomp.h are run concurrently a corrupted
version of seccomp.h will be generated. Amongst other problems this can
cause spurious failures on clang-tidy.
Alter seccomp.sh to build the output in a temporary file and atomic move it
to seccomp.h, so concurrent invocations will still result in valud output.
