Remove lz4 build with custom memory configuration

lz4 позволяет определить параметр memory на этапе компиляции. Этот параметр задаёт трейдофф между скоростью и степенью сжатия.

Сейчас этот параметр используется только в blockcodecs. Поиск по аркадии не находит упоминания этих кодеков. Возможно, что они вообще не используются.

Так как параметр на этапе компиляции требует хаков на уровне сборки и усложняет апдейт lz4, предлагаю удалить эти хаки, и оставить только default уровень сжатия (параметр 14).
