Revert "Fix build docker with sqlite3 musl error (#234)"

The commit 031e41a is a temporary workaround to fix musl build error, and now to remove `CGO_CFLAGS="-D_LARGEFILE64_SOURCE"` for building docker image, because go-sqlite3 library was upgraded to `1.14.19` [^1] and the musl build was fixed in go-sqlite3 version `1.14.19` [^2].

This reverts commit 031e41a (refer PR #234).
