ipmi-net: ensure eth device present

Some OpenBMC systems may support a mix of eth0-only and eth0/eth1 ports
on their BMC device. In some cases, this support may be in a shared
flash image that supports both systems.

For example, IBM is building a system under the "p10bmc" bitbake machine
that only has a single ethernet port, eth0, wired up on it. The system
is still utilizing an AST2600, but only wired eth0 out of the system for
cost purposes.

Since the "p10bmc" machine is a shared target there is no way to remove
services that assume eth1 is present during the build process. Instead,
rely on the fact that the device will be present in /sys/class/net/
if in fact the system supports the network device.

Tested:
- Verified that a p10bmc Rainier machine with 2 eth ports still ran
  these units for both ports
- Verified that a p10bmc Bonnell machine with only eth0 ran these units
  for eth0 but not eth1
