Subject: [PATCH] Debian info_installed compatibility (#50453)

Remove unused variable

Get unit ticks installation time

Pass on unix ticks installation date time

Implement function to figure out package build time

Unify arch attribute

Add 'attr' support.

Use attr parameter in aptpkg

Add 'all_versions' output structure backward compatibility

Fix docstring

Add UT for generic test of function 'info'

Add UT for 'info' function with the parameter 'attr'

Add UT for info_installed's 'attr' param

Fix docstring

Add returned type check

Add UT for info_installed with 'all_versions=True' output structure

Refactor UT for 'owner' function

Refactor UT: move to decorators, add more checks

Schedule TODO for next refactoring of UT 'show' function

Refactor UT: get rid of old assertion way, flatten tests

Refactor UT: move to native assertions, cleanup noise, flatten complexity for better visibility what is tested

Lintfix: too many empty lines

Adjust architecture getter according to the lowpkg info

Fix wrong Git merge: missing function signature
