ethumb: fix setup related API problem

Summary:
setup related API was not working at all due to below problems

1. dbus type signature is wrong. it's array of dictionary not array of struct
2. since quality value was assigned to compress value, there was a problem during saving png image (out of bound)
3. orientation_set API was not working except NONE and ORIGINAL

@fix

Test Plan: make thumbnail by using elm_thumb_add -> orientation set to 90 CCW -> check whether image is rotated properly or not
