`std.posix.sendfile()` fails to compile on 32-bit FreeBSD

[alexrp]

For arm-freebsd.14.0-eabihf:

/home/alexrp/Source/ziglang/zig-bootstrap/out/host/lib/zig/std/posix.zig:6470:36: error: @bitCast size mismatch: destination type 'usize' has 32 bits but source type 'i64' has 64 bits
                const amt: usize = @bitCast(sbytes);
                                   ^~~~~~~~~~~~~~~~

I'm in the midst of deleting this function in this branch

Ok, I'll just wait for that before going further with this then.
