minigbm: add bytes per pixel function

We were using the drv_stride_from_format as a shorthand to calculate
bytes per pixel. This is incorrect with the addition of
DRM_FORMAT_YVU420_ANDROID, which always aligns to 16 bytes.

Let's have a separate bytes_per_pixel function to better express what
we want.
