            [bugfix] Declare bundled 'ed25519-ref10' in 'client_ed25519' plugin

The 'client_ed25519' authentication plugin bundles a modified copy of
the SUPERCOP/NaCl Ed25519 "ref10" reference implementation by
D.J. Bernstein et al. ('plugins/auth/ref10/').

The code is public domain and unversioned (SUPERCOP uses dated
snapshots, not releases; the ref10 field arithmetic has been stable
since ~2012). MariaDB's copy modifies 'sign.c': the original
'crypto_sign()' is replaced with 'ma_crypto_sign()', which takes a
password and hashes it internally instead of accepting a pre-derived
secret key. This modified API is not exposed by any system library,
so the code cannot be unbundled.

Per Fedora Packaging Guidelines, bundled libraries must be declared
even when unbundling is not possible. Also add
'LicenseRef-Fedora-Public-Domain' to the 'License' field for the
bundled public domain code.
