NetworkManager package and PAM stat files fixes

• Use proper NetworkManager package for ubuntu2204 and ubuntu2404.
• Resolved issue where using the same register variable outside and inside the block was causing failures.

Description:

• Update logic to make sure the NetworkManager package for ubuntu2204 and ubuntu2404 is being installed.
  • The updated logic makes sure that if future products useplatform_package_overrides.NetworkManager that package gets used.
• Resolved issue where using the same register variable outside and inside the block was causing failures.

Rationale:

• When testing the Ansible playbook for ubuntu2404 I ran into two issues:

  • The playbook was trying to install and look for the NetworkManager package calledNetworkManager, however for ubuntu2204 and ubuntu2404 the correct package name isnetwork-manager. This was noted in the product files, it just was not being overriden.
  • When only the register variable ofresult_pam_file_present was being used for both inside and outside of a block it would cause strange errors.

• FixesNetworkManager package not overriden for ubuntu 22.04 and 24.04 #14038
