[SDK] crt/sys/stat.h: Import MinGW-w64 patch "Change _S_IFBLK from 0x3000 to 0x6000"

Mingw-w64 commit id 850703ae46e1971c5789fa1bdd802fb9692c41c9 by Daniel Starke via Mingw-w64-public <[email protected]>

headers: Change _S_IFBLK from 0x3000 to 0x6000

The _S_IFBLK macro, used to identify block special files in file systems, is
being updated from 0x3000 to 0x6000. This change aligns mingw-w64 with the more
commonly used value across Unix-like systems and other C libraries.

The old value of 0x3000 may have caused compatibility issues when working with
code that assumes the standard 0x6000 value for S_IFBLK.

This update improves cross-platform compatibility and consistency with other
systems, making it easier to write portable code that deals with file type
identification. It also reduces potential confusion and errors that might arise
from the non-standard value.

One of these is for example python. This is only an example. It does not change
the fact that python should be more careful about actual value implementation.

Note that the current value implies character device + FIFO instead of
character device + directory.
