fakeroot: fix to work with glibc 2.33

The following commit removed _STAT_VER definitions from glibc:
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=8ed005daf0ab03e142500324a34087ce179ae78e

That subsequently broke fakeroot:

https://forum.openwrt.org/t/unable-to-build-toolchain-fakeroot-fails-perhaps-others-after-it/87966

Make the patch based on Jan Pazdziora's suggestion from here:
https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/SMQ3RYXEYTVZH6PLQMKNB3NM4XLPMNZO/

Add wrappers for newly exported symbols in glibc.

Apply patch from Debian to fix warnings in fts_read and fts_children:

Fix __xmknod{,at} dev pointer argument. Switch default to assume * and
not the absence of *. On glibc 2.33+, there is no definition for these
functions in header files, so the compile test doesn't work. But, we
can default to using the pointer (as is the case with newer glibc), and
use the header file on older platforms to fail the test and use no pointer.

Tested on my x86_64 Arch Linux machine, fakeroot unit tests pass.
Also tested by building various .ipks and examining the tar contents, to
ensure that the owner uid/gid was 0/0.
