[Buildroot] [PATCH 1/1] package/botan: needs C++20

[Fabrice Fontaine]

C++20 is mandatory since bump to version 3.2.0 in commit
2f8feb66204ff661e9fd5f508e2dfd1ebc0f2813 and
https://github.com/randombit/botan/commit/e2efb744ceda875b193bc5ce589f2c45ceaa3a82
resulting in the following build failure:

powerpc-linux-g++.br_real: error: unrecognized command line option '-std=c++20'; did you mean '-std=c++2a'?

BR2_TOOLCHAIN_HAS_GCC_BUG_64735 dependency can be dropped as gcc > 7 is
not affected by this bug

Fixes: 2f8feb66204ff661e9fd5f508e2dfd1ebc0f2813
