Add python-ldap deps for zuul test

Zuul tests are failing to build python-ldap due
to some missing binary pkg dependencies [1].
Added them using bindep following the solution
on the gui repo [2, 3]

[1] https://zuul.opendev.org/t/openstack/build/8356394372e24999b27e1a0251e1d919
[2] https://review.opendev.org/c/starlingx/gui/+/894397
[3] https://review.opendev.org/c/starlingx/gui/+/885834

Test Plan:
pass: tox --notest -epylint -vv --skip-missing-interpreters=false
