games-strategy/0ad: Bump to alpha25b and EAPI=8

Upstream bumped 0ad with some fixes, quoting upstream:

- Ranked matches did not longer grant points in the lobby.
- Mod installation no longer require restart.
- Mod installation no longer prints errors when installing mods
  by double-clicking
- Mod installation now overwrites the existing mods to allow
  for easier updates.
- Fishes are now easier to spot on lowest settings with
  the addition of seagulls.

For their full announcement see:
https://play0ad.com/re-release-of-0-a-d-alpha-25-yauna/

This bump hops to EAPI=8 as all used eclasses support it now
and the bump drops an forgotten comment about the bundled premake5.

Additionally it adds distfile signature verification using
the verify-sig eclass calling app-crypt/minisign manually.
