Change evas gl option to option bits.

[Problem] efl version >= 1.13.2 deprecates mem optimize
environment flags.

[Solution] Add efl mem optimize flags to option bit.
Environment variables for evas surface are not supported
from efl 1.13.2. Environment variables are supported only
for evas engine. With mem optimize option for evas surface,
intermediate buffers created by evas are generated on demand.
16MB 3D memory is reduced.
