Any attest-key request or BYO request goes software unconditionally.
Drops the alias-Elvis lookup and the nspace fallback added by the
17c6312 -> eea6001 -> be04f16 revert/restore churn, both of which
silently missed when callers (Shizuku, post-restart sessions) did
not share an in-memory KeyIdentifier(uid, alias) with the attest
key originally registered in attestationKeys.
The (shouldPatch && isAttestKeyRequest) clause is subsumed by the
broader isAttestKeyRequest clause.
