[Buildroot] [git commit] package/busybox: fix build with glibc 2.31

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=13f2d688a24f47446af236829bd6ca194d5aea5b
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Busybox 1.31.1 fails to build with glibc 2.31 due to the removal of
stime() from glibc. Pull a patch already applied upstream to fix the
problem.

The patch was rebased on version 1.31.1 to minimize the change, since
the original one depended on a previous commit which is not worthwhile
to pick.

+Subject: [PATCH] Remove stime() function calls
+
+stime() has been deprecated in glibc 2.31 and replaced with
+clock_settime(). Let's replace the stime() function calls with
+clock_settime() in preperation.
