Android: tuning Exynos HW H264 encoding performance.

Exynos H.264 HW encoder implementation assumes constant frame rate and
does not adjust when actual frame rate is different from the original value.
For example,  when encoder is intialized with 30fps and we want to adapt to
1000kbps@15fps now, we will only get 500kbps@15fps. So we will adjust the
target bps to 2000kbps@15fps to achieve the expected 1000kbps.
