Commit 3da874371 ("libsodium: include ed25519_core in minimal build")
broke the build of PyNaCl. Add patch to always include all ed25519
functions which are now always covered even if libsodium is built with
the MINIMAL option.

Fixes https://github.com/openwrt/packages/issues/13016
Patch [1] broke compilation for python-pynacl.

The fix is to patch PyNaCl to consider that
PYNACL_HAS_CRYPTO_SCALARMULT_ED25519 is always available.
