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
- Modify command parsing code to add support for e1000 and adjust tests
- Add net-e1000 test

I think it's strange that you need to pass a virConnectPtr around to
your command-line builder functions for caps. In the qemu driver, use of
virConnectPtr has been eliminated wherever possible (it's completely
absent from qemu_command.c). We just get the qemuCaps directly from the
driver object.

Flipped ret value and renamed out to cleanup. Generally, I just need to
add a helper function for these probes as they're very similar and I'm
planning to add some more cap checks.
