Fix ldap dir on ansible playbook for backup roles

when running backup on Debian, ansible throws an error
on ldap db backup task.
error: "slapcat: 'bad configuration directory!'"

that's because ldap configuration directory changed on
debian from openldap to ldap

the fix this is to indentify the os distribution that
is currently using and do a conditional on ansible, to
differentiate the task on debian from centos, to be able
to fetch information from the correct directory depending
on the os.

Test Plan:
PASS: Build an image on Debian
PASS: Build an image on CentOS
PASS: Create backup on Debian
PASS: Create backup on CentOS
