stagefright: set scaling mode for blank frames in ACodec

Analogous to 1d5ac80d0c6d3deabcc9e9b4abc9e3ef536aeb27
(by jgennis), this sets the scaling mode for the ANativeWindow
to SCALE_TO_WINDOW prior to pushing the blank frames during
decoder tear down.

Without this, the window defaults to FREEZE and SF ignores the
new frames.
