gst1-plugins-ugly: fix x264 compile failure

Add upstream patch to fix compile with latest x264 library.

Fixes [1]:

  gstx264enc.c: In function 'plugin_init':
  gstx264enc.c:2900:36: error: 'x264_bit_depth' undeclared (first use in this function); did you mean 'x264_picture_t'?
     default_vtable.x264_bit_depth = &x264_bit_depth;
                                      ^~~~~~~~~~~~~~
                                      x264_picture_t

+Subject: [PATCH] x264enc: fix build with newer x264 with support for multiple
+ bit depths
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+libx264 used to be built for one specific bit depth, and if we
+wanted to support multiple bit depths we would have to dynamically
+load the right .so from different paths. That has changed now, and
+libx264 can include support for multiple depths in the same lib,
+so we don't need to do the dlopen() dance any more. We'll keep
+the vtable stuff around until we can drop support for older x264.
