Added function to rename .ctors sections into .init_array in cuda libraries

Добавил функцию, чтобы все библиотеки из CUDA пакетов, которые статически линкуются, гарантировано имели символы в секции `.array_init`, а не в `.ctors`, как происходит сейчас.

В противном случае некоторые библиотеки не работают в случае статической линковки (например, `nvrtc`).
