Serial device fix

When using nmdm(4) as a serial device, a VirtualBox VM will not start until the corresponding nmdm(4) peer device is open.

For example, if you configure a test_vm like this:

  VBoxManage modifyvm test_vm --uart1 0x3F8 4 --uartmode1 /dev/nmdm0A

it will hang at boot forever until /dev/nmdm0B is accessed.

It possibly happens on actual serial devices too, but I don't have one to test.

This case is already handled for Linux so we just have to expand the check to cover FreeBSD too.
