Subject: [PATCH] FFI sendfile64 -> sendfile

sendfile64 does not exist on Alpine/MUSL,
it exists as "sendfile" and is 64b by default
This fix is necessary to build this package on Alpine/musl.

Full compatibility with glibc 32b may require preprocessor conditionals that are not included in this minimal fix
