On Linux ENODATA is defined but on BSD, and MacOSX ENOATTR is used
instead. Defined ENODATA to be ENOATTR when the system is not Linux.
v2: Replaced ENODATA and ENOATTR with -EFAULT that is exists everywhere

The meson-windows-vs2019 job was going down the `!defined(WIN32)` path,
leading to a broken build once that path contained non-windows code.

This allows communicating that it wasn't possible to determine whether
the two file descriptors reference the same file description. When
that's the case, log a warning in the amdgpu winsys.
In turn, remove the corresponding debugging output from the fallback
os_same_file_description implementation. It depends on the caller if
false negatives are problematic or not.

Use fstat() only to pre-allocate a big enough buffer.
This fixes a race where if the file grows between fstat() and read()
we would be missing the end of the file, and if the file slims down
read() would just fail.
