bisq2: add aarch64-linux support

- Add aarch64-linux as a platform.
- Use both GPG keys for signature verification.
- Remove lib anti-pattern in the meta attribute.

The bisq2 deb package is usually signed by one of two GPG keys.
Instead of having to modify the package to use the correct key,
this change adds both keys to the key ring. GPG will produce a
successful verification as long as one of the keys verifies.
