Bug#863139: mongo-tools FTBFS on arm64: _build/src/github.com/spacemonkeygo/spacelog/capture_other.go:26: undefined: syscall.Dup2

[Edmund Grimley Evans]

The fix is described here:

https://github.com/spacemonkeygo/spacelog/issues/6

Add golang-golang-x-sys-dev to the Build-Depends, and in capture_other.go
replace "syscall" with "golang.org/x/sys/unix",
and each "syscall." with "unix.".
