[PATCH 4/9] build: remove check for MACVLAN_MODE_PASSTHRU



macvlan support was added to the Linux kernel in 2.6.33, but
MACVLAN_MODE_PASSTHRU wasn't added until 2.6.38, so a workaround had
been put in place to define that constant on those few systems where
it was missing. It's useful like was probably 6 months at most, but
it's been there for over 10 years.
