[libvirt] [PATCH 2/2] bhyve: add e1000 nic support

Recently e1000 NIC support was added to bhyve; implement that in
the bhyve driver:
- Add capability check by analyzing output of the 'bhyve -s 0,e1000'
command
- Modify bhyveBuildNetArgStr() to support e1000 and also pass
virConnectPtr so it could call bhyveDriverGetCaps() to check if this
NIC is supported
- Add net-e1000 test
