Subject: Remove LFS64 calls and set _FILE_OFFSET_BITS=64

Musl 1.2.4 made the LFS64 interfaces only available when
_LARGEFILE64_SOURCE is defined, and they will be removed altogether in
Musl 1.2.5. This commit replaces the LFS64 calls with their non-LFS64
versions and defines _FILE_OFFSET_BITS=64, which makes all interfaces
64-bit.
