Updated `netstat` command to minimize its output with `-t` and `-l` flags. Refactored regex on `libmachine/provision/utils.go`:`checkDaemonUp` to avoid `matchNetstatOut` returning `true` when remote machine has a similar port to dockerPort listening (e.g. dockerPort := 2376 and remote machine has port 23760 listening). Refactored `utils_test.go` with more accurate `netstat` output. Signed-off-by: Tiago Pires <tandrepires@gmail.com>
