[Buildroot] [PATCH] swig: add symlink to /usr/bin/swig2.0

[Jérémy Rosen]

the cmake detection script provided with cmake will first look for a
binary called swig2.0 then for a binary called swig

swig-host only installs a binary called swig and gets overridden by the
version installed by the host distro. This symlink prevents that from
happening
