videoio: drop unnecessary offset for accessing video output buffer

Browse Source 
Fix: #21021

NDK API AMediaCodec_getOutputBuffer() returns MediaCodecBuffer::data()
which is actually ABuffer::data(). The returned buffer address is already
adjusted by offset.

More info:
    ABuffer::base() returns base address without offset
    ABuffer::data() returns base + offset
