Camera: fix testCapabilities

Bind tonemap curve and color correction aberration mode key to
MANUAL_POSTPROCESSING capability instead of FULL hardware level.
For MANUAL_POSTPROCESSING capability, check:
    1. CONTRAST_CURVE tonemap mode is supported
    2. OFF color aberration mode is supported

Also fix constant of saturation level in AllocationTest.
