[Android] Refine the callback function of compressor.

This patch is to refine the feature of compressor.
optparse stores the converted value when we use '--compressor'
at the first time. Then we use '--compressor=css', optparse
does not consume the argument.
Add 'type' and 'nargs', they instruct optparse to consume the
argument and convert the parameter to related type.
Add test case for this feature.
