[21.02] python-pynacl: missing ed25519 patch

[mcbridematt]

After 4f7fcd9 ("libsodium: include ed25519_core in minimal build") was backported into the 21.02 branch, python3-pynacl now fails to compile:

After cherry-picking ccd3b6c ("pynacl: fix build with updated sodium-minimal patch") it now compiles again.

The master branch has pynacl 1.5.0 which supersedes the 1.4.0 in 21.02
