This test is incorrect, and we do not need the modprobe. If macvlan is a
module, it is automatically modprobed when the first macvlan link is
added. Also, the /sys directory referred to in the test does not exist
if macvlan is built into the kernel.

Since commit 683a21b0a in Feburary 2011, iproute2 has been required for
new VLAN configuration. MACVLAN is also impossible to configure without
iproute2. However we did not check if iproute2 was actually in the
modules for a given interface, so it could end up hanging or giving
weird errors. Check for iproute2 before usage now.
