virt-host-validate-bhyve: replace if_tap check with if_tuntap check

The tun(4) and tap(4) FreeBSD device drivers were merged
into a single tuntap(4) driver back in 2019 and now it's effective
for all supported FreeBSD versions.

As the virt-host-validate-bhyve still checks for the "if_tap" module,
it does not report actual status on the supported FreeBSD releases.
Fix by checking for the "if_tuntap" module instead.
