[Buildroot] [PATCH] package/swig: create a symlink for swig3.0

[yegorslists at googlemail.com]

From: Yegor Yefremov <yegorslists at googlemail.com>

For now swig package creates a symlink to the latest swig version
i.e. swig4.0. If the host already has both CMake 3.10 and earlier
swig version then the earlier version (swig2.0 or swig3.0) will
be detected. This happens because CMake 3.10 doesn't know about
swig4.0 and thus searches for swig3.0 first and finds it on the
host.

With the new symlink CMake will find buildroot's swig binary.
