lib/crypto: curve25519-hacl64: Fix older clang KASAN workaround for GCC

Commit 2f13daee2a72 ("lib/crypto/curve25519-hacl64: Disable KASAN with
clang-17 and older") inadvertently disabled KASAN in curve25519-hacl64.o
for GCC unconditionally because clang-min-version will always evaluate
to nothing for GCC. Add a check for CONFIG_CC_IS_CLANG to avoid applying
the workaround for GCC, which is only needed for clang-17 and older.
