net-misc/openvswitch: add USE=unwind

Building net-misc/openvswitch on a host with sys-libs/libunwind
installed results in several binaries being linked to libunwind.so.

As net-misc/openvswitch lacks a dependency on sys-libs/libunwind,
installing a binpkg created on such host will result in broken binaries.

There is no configure option to disable libunwind, and upstream enables
the dependency unconditionally in their RPM spec, but as we support
architectures that do not support libunwind, this is not an option.

Add a USE flag to toggle libunwind via the autoconf macro.
