xmlsec: handle missing EqualDistinguishedNames

This is just a hack. A more correct fix would be to condition
the whole xmlsecurity support in the various LO modules.

The non-NSS build now fails, because it misses the
EqualDistinguishedNames, which is non-trivial to implement.

This is the consequence of commit
1d3da3486d "xmlsecurity: add
EqualDistinguishedNames()" and commit
5af5ea893b "xmlsecurity: improve
handling of multiple certificates per X509Data".

FWIW: one could also use OpenSSL i2d_X509_NAME and X509_NAME_cmp
to implement this functionality, but it looks like it requires
some ANS.1 input to begin with (maybe i2s_ASN1_* can be used).
And then you would still miss some certificate store integration.
