screenrecord: allow force landscape mode

Some devices' hardware encoder do not support encoding over a

height in portrait mode. Add a mode which uses landscape encoding
and rotation hint to overcome the limitation.

libstagefright: Fix timestamp corruption during offload playback

-Timestamp gets corrupted at EOS of offload playback.
-This happens because the number of samples played returned from
 HAL could be zero if playback has reached EOS and if compress
 handle is invalid / closed.
-If HAL has posted EOS  avoid the update of real time and media
 time with the timestamp from HAL.
