config/common: Clean up debug packages

 * Include all debug packages via PRODUCT_PACKAGES_DEBUG.

 * Remove oprofiled and sqlite3 from the list, because the former
   no longer exists and the latter is already part of
   build/target/product/core_base.mk. Also remove gdbserver, since
   it's already built by default.
