[IMP] hr_*: Improve the search views for department fields

1 Display department on manager list views
==========================================

On the manager list views (Leaves/Allocations to approve), the department
is not displayed. Display it on these list views, but keep it hidden for the
employee views.

2 Allow to search employees on allocations
==========================================

3 Search on department and on children departments
==================================================

Currently when searching on a department (on the employee view for example)
we only retrieve employees from the specific department. It should return
all the employees from the department and also from its children
departments, like for partners or companies.

Adapt all the search view where a department field is used by
specifying a 'child_of' operator.
