mk-ca-bundle: remove CKA_NSS_SERVER_DISTRUST_AFTER conditions

Browse Source 
The script's previous treatment of this meta-data was a
misunderstanding. (Added in 1ebc53df25) The mistrust is not for
the root cert at this date (it would simply be removed from the bundle
then instead) but for created server certificates:

    If a builtin certificate has a CKA_NSS_SERVER_DISTRUST_AFTER
    timestamp before the SCT or NotBefore date of a certificate that
    builtin issued, then clients can elect not to trust it.

That is however information that cannot be provided in the generated PEM
output.

Fixes #15547
Reported-by: Andrew Ayer
Closes #15552
