update openldap root dse fp pattern

[gustavoluvizotto]

Description

Updated the fingerprint matching pattern to identify more OpenLDAP instances.

Motivation and Context

When queried by the RootDSE, OpenLDAP servers could be identified under the objectClass attribute name or structuralObjectClass attribute name. Hence, it is necessary to adapt the current matching pattern to identify such servers.

Here are a few examples:
With objectClass:
https://search.censys.io/hosts/61.222.164.42/data/table#389-TCP-LDAP
With structuralObjectClass:
https://search.censys.io/hosts/213.55.162.229/data/table#636-TCP-LDAP

Can someone review my PR?

I think this might be missing padding or similar; Looks like the the Go test suite fails:

time="2024-07-02T14:38:06Z" level=error msg="error verifying examples in recog-content/xml/ldap_searchresult.xml: base64: (?i-s:\\x04..PENLDAPROOTDSE): illegal base64 data at input byte 60 (BBVzdHJ1Y3R1cmFsT2JqZWN0Q2xhc3MxEQQPT3BlbkxEQVByb290RFNFMBwEDQ)"

indeed. I updated the b64 data. Can you trigger the test again? Thank you

[adfoster-r7]

Tests are passing now; thanks!
