package/mariadb: fix build with fmt >= 11.0.1

MariaDB is failing to build since commit 6b86f076c3 "package/fmt: bump
to version 11.0.1" with output:

    /buildroot/output/build/aarch64-buildroot-linux-gnu/sysroot/usr/include/fmt/base.h:1402:29: error: passing 'const fmt::v11::formatter<String>' as 'this' argument discards qualifiers [-fpermissive]
     1402 |     ctx.advance_to(cf.format(*static_cast<qualified_type*>(arg), ctx));
          |                    ~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This commit is fixing the issue by adding an upstream patch, rebased
on the package version.

+Subject: [PATCH] MDEV-34206 compile failure: fmt use incompatible with
+ libfmt-10.2.[2]+
+
+Upstream libfmt commit https://github.com/fmtlib/fmt/commit/d70729215fba1d54862e407b626abf86ddf409bf
+now requires the format function to be const.
+
+Adjust the function prototype so it is const and can compile.a
