On darwin d_seekoff exists, but is optional and does not seem to
be commonly used by file systems. Use `telldir` instead to obtain
the seek offset and inject it into d_seekoff, and create a
qemu_dirent_off helper to call it appropriately when appropriate.

[Will Cohen: - Adjust to pass testing
- Ensure that d_seekoff is filled using telldir
on darwin, and create qemu_dirent_off helper
to decide which to access]

[Will Cohen: - Ensure that telldir error handling uses
signed int
- Cleanup of telldir error handling
- Remove superfluous error handling for
qemu_dirent_off
- Adjust formatting
- Use qemu_dirent_off in codir.c
- Declare qemu_dirent_off as static to prevent
linker error
- Move qemu_dirent_off above the end-of-file
endif to fix compilation]
