Fix incorrect error check when verifying SCT

Introduced in sigstore#1396, this incorrectly checked err instead of verifySctErr. This resulted in no error being printed when SCT validation failed. Verified this is working correctly now with local testing. Signed-off-by: Hayden Blauzvern <[email protected]>
