sign-file,extract-cert: avoid using deprecated ERR_get_error_line()

Browse Source 
ERR_get_error_line() is deprecated since OpenSSL 3.0.

Use ERR_peek_error_line() instead, and combine display_openssl_errors()
and drain_openssl_errors() to a single function where parameter decides
if it should consume errors silently.
