Fix build docker with sqlite3 musl error (#234)

Fix build docker error in github actions job#923. [^1]

This is now broken in latest `golang:alpine` image (from alpine3.18 to alpine3.19).
Alpine 3.19 was released on 2023-12-07. [^2]
It is shipped with gcc 13.2 and musl-dev 2.14. [^3]
The LFS64 interfaces were marked as deprecated for musl 1.2.4. [^4]

As a temporary workaround, builds broken by this change can be fixed short-term by adding `-D_LARGEFILE64_SOURCE` to `CFLAGS`, but should be fixed to use the standard interfaces.
