Bring over change from meta-openembedded

This is the change required for the problem discussed in the email w/ the subject:
iproute2 - meta-openembedded/libmnl and Yocto Project compat

I could find no other way to remedy the Yocto Project compat checker against meta-openembedded without moving this change from there to here. A corresponding patch has been sent to the meta-openembedded mailing list.

iproute2: Default to tipc enabled, and include libmnl dependency

iproute2 has the ability to include a tipc tool. When enabled this requires the libmnl package (formerly supplied by meta-openembedded). So both are needed at the same time.

The change itself is needed because of the tipc-utils package (in meta-openembedded) which RDEPENDS on iproute2-tipc. Without this package the yocto-compat-layer script indicates there is no way for me to have meta-openembedded pass the checker. This is because meta-openembedded is not allowed to just enable 'tipc' on it's own. (A layer may not make distro wide changes without a user saying to do it.) The checker script invokes bitbake -S none world, which will fail on dependency resolution due to there being no iproute2-tipc package. The tipc-utils package does not have a way to check the PACKAGECONFIG of the iproute2 package so disable itself if the dependency can not be met. So the default system behavior needs to be:

iproute2 w/ tipc enabled
tipc-utils RDEPENDS on iproute2-tipc

Yes, but I feel this needs to be re-considered. At present we can't pass the Yocto Project compliant test (with meta-openembedded included) without enabling tipc for iproute2. This justification is hopefully enough to conclude moving libmnl into oe-core is 'acceptable risk' at this point in the system.
