Subject: [PATCH] direct_mmap: Use off_t on linux

off64_t is not provided without defining _LARGEFILE64_SOURCE on musl
this define is not defined automatically like glibc where it gets
defined when _GNU_SOURCE is defined. Using off_t makes it portable
across musl/glibc and for using 64bit off_t on glibc 32bit systems
-D_FILE_OFFSET_BITS=64 can be defined during build via CXXFLAGS
