package/botan: add patch for CVE-2024-50382 & CVE-2024-50383
Fixes the following vulnerabilities:
- CVE-2024-50382:
Botan before 3.6.0, when certain LLVM versions are used, has compiler-
induced secret-dependent control flow in lib/utils/ghash/ghash.cpp in
GHASH in AES-GCM. There is a branch instead of an XOR with carry. This
was observed for Clang in LLVM 15 on RISC-V.

- https://github.com/randombit/botan/commit/53b0cfde580e86b03d0d27a488b6c134f662e957
- CVE-2024-50383:
Botan before 3.6.0, when certain GCC versions are used, has a
compiler-induced secret-dependent operation in lib/utils/donna128.h in
donna128 (used in Chacha-Poly1305 and x25519). An addition can be
skipped if a carry is not set. This was observed for GCC 11.3.0 with
-O2 on MIPS, and GCC on x86-i386. (Only 32-bit processors can be
affected.)
