gst1-vaapi: bump to 1.14.1

- add upstream patch to fix the following compile failure:

  gstvaapipluginutil.c:259:12: error: ‘GstGLDisplay’ undeclared (first use in this function); did you mean ‘GstVaapiDisplay’?
             (GstGLDisplay **) & plugin->gl_display,
              ^~~~~~~~~~~~
              GstVaapiDisplay
  gstvaapipluginutil.c:259:12: note: each undeclared identifier is reported only once for each function it appears in
  gstvaapipluginutil.c:259:27: error: expected expression before ‘)’ token
             (GstGLDisplay **) & plugin->gl_display,
                             ^

Also add hash for license file.
