gst-fsl-plugin: fix segfault due to not found library

The gst-fsl-plugin package tries to 'dlopen' a library using the
symbolic link that points to the library file. But that symbolic link is
only installed with the development package (PN-dev), not with the
normal package.

This commit adds a patch that uses the soname of the library in dlopen
call.

+Subject: [PATCH] Use library's SONAME in dlopen
+
+The 'libmfwba.so' symbolic link is only installed with the development
+package, and without that symlink some gstreamer pipelines (mostly using
+mfw_isink) fail with:
+
+Can not open dll, libmfwba.so: cannot open shared object file: No such file or directory.
+Caught SIGSEGV accessing address (nil)
