Merge pull request #21140 from ConiKost/musl

* src/openrct2/core/FileStream.cpp: drop ftello64, fseeko64

The static usage definition of ftello64 and friends is not correct.
While this currently works on glibc, this breaks on musl, as musl
already is LFS aware. The solution is to drop this and add instead
'-D_FILE_OFFSET_BITS=64' to the build system.

* CMakeLists.txt: add D_FILE_OFFSET_BITS=64
