rg_etc: Correct ifdef to keep function available for debug build

In the nightly builds we have debug enabled and this spotted the case where
rg_etc1_solution_coordinates_block_colors_get is actually still used:

lib/eet/.libs/libeet.so: undefined reference to `rg_etc1_solution_coordinates_block_colors_get'

Showed only after we switched back from release to dev mode.

@fix
