egl/android: Restrict minimum triple buffering for android color_buffers
The patch restricts triple buffering as minimum at driver for android
color_buffers in order to fix onscreen performance hit for T-Rex and
Manhattan.
v2: Update min_buffer check condition (Tapani Pälli)
v3: further code cleanup (Eric Engestrom)
Closes: https://gitlab.freedesktop.org/mesa/mesa/issues/2332
Fixes: 0661c357c60 ("egl/android: Update color_buffers querying for buffer age")
