Revert "Revert "Move error_code.h into otautil.""

This reverts commit 26436d6d6010d5323349af7e119ff8f34f85c40c to re-land
"Move error_code.h into otautil.".

This way it stops requiring relative path ".." in LOCAL_C_INCLUDES
(uncrypt and edify). Soong doesn't accept non-local ".." in
"local_include_dirs".

This CL needs to land with device-specific module changes (e.g. adding
the dependency on libotautil).
