Also fix the license information: in older versions the test programs
were GPL 3 licensed, but meanwhile it changed to BSD license.
But since this package only packages the library itself, we can
safely focus only on the LGPL here which covers the library itself.

While at, fix a minor nitpick during library symlink installation.
