syscall: fd passing fails on FreeBSD

[bradfitz]

This test fails on FreeBSD:

http://code.google.com/p/go/source/detail?r=160ec5506cb7740be6702e5996fa05059578c4a5

The test is now removed from the tree, so:

$ hg update -C 160ec5506cb
and then edit src/pkg/syscall/passfd_test.go to change "probablyfreebsd" to
"freebsd", then watch it fail:

ReadAll reads "", <nil>, not the expected string.

I tried to run it under truss -f to watch the system calls, but that hung my (remote)
VM, and now I no longer have a FreeBSD machine.

Thanks to a tip from dho I believe I am a step closer to solving this problem. On the
32bit systems I have access too freebsd/386 9.1 and freebsd/arm 10-CURRENT, the
passfd_test.go tests pass.
