Bug fixes

sign: verify signed files against their transparency log entry (#611)

SignFile verified the signature and certificate it had just written against the local clock, without the transparency log. The Fulcio certificate of keyless signing is only milliseconds old at that point, so a clock behind the one of Fulcio saw it as not yet valid, and signing failed with verify bundle without transparency log, which requires a certificate that is still valid: failed to verify leaf certificate. This broke blob signing in krel release at random.

• Signing now verifies the bundle against the transparency log entry it created, at the time the log recorded the signature, before writing the signature and certificate. A failed check leaves no .sig or .cert behind.
• SignFile no longer verifies the written files once more, so the VerifyFileInternal call after SignFileInternal is gone, which tests stubbing signfakes.FakeImpl may notice.
• Key based signing without PublicKeyPath failed before too; it now fails before writing anything, with an error that names the missing public key.

Looks like sigs.k8s.io/release-sdk is updatable in another way, so this is no longer needed.
