Use an extended com_err hook in klist

Add an adapted version of extended_com_err_fn from kinit to klist and
use it.  In do_ccache(), rely on the ccache type to set a reasonable
message if krb5_cc_set_flags() or krb5_cc_get_principal() fails due to
a nonexistent or unreadable ccache, and don't confuse the user with
the name of the ccache operation that failed.
