The posix_fallocate syscall returns the result in r1 rather than in
errno:
> If successful, posix_fallocate() returns zero. It returns an error on failure, without
> setting errno.

Adjust the PosixFallocate wrappers on freebsd to account for that.
Also, CL 479715 used the same syscall wrapper for 386 and arm. However,
on arm the syscall argument order is different. The wrapper was
generated using mksyscall.go from the golang.org/x/sys/unix package,
adjusting the r1 check correspondingly.

64-bit syscall arguments need to be passed as two 32-bit arguments on
32-bit freebsd.
