wpesrc: fix possible small deadlock on shutdown
Problem is that unreffing the EGLImage/SHM Buffer while holding the
images_mutex lock may deadlock when a new buffer is advertised and
an attempt is made to lock the images_mutex there.
The advertisement of the new image/buffer is performed in the
WPEContextThread and the blocking dispatch when unreffing wants to run
something on the WPEContextThread however images_mutex has already been
locked by the destructor.
Delay unreffing images/buffers outside of images_mutex and instead just
clear the relevant fields within the lock.
