Remove the "If only executable code is distributed..." paragraph from the license text. Everything now uses a normal MIT license. The only code from Khronos that's included in libglvnd is the EGL/GL header and XML files, which do not contain that paragraph. Fixes https://gitlab.freedesktop.org/glvnd/libglvnd/-/issues/221
