This should eliminate sporadic failures, like the known double close in "seccomp".

This removes the requirement to call fmsg.Exit on every exit path, and enables direct use of the "log" package. However, fmsg.BeforeExit is still encouraged when possible to catch exit on suspended output.

Turns out the doc comment on os.File was lying about its methods being safe for concurrent use. The race detector picked up a data race from concurrent use of Fd and Close.
This change eliminates that by calling Fd in the prepare routine.

This also does not require the libc tmpfile call.
BPF programs emitted by libseccomp seems to be deterministic. The tests would catch regressions as it verifies the program against known good output backed by manual testing.
