login: T5875: fix corner case for KeyError: 'getpwuid(): uid not found: XXXX'

Commit 1b364428f ("login: T5875: restore home directory permissions only when
needed") added logic to chown the users home directory if it's UID changes.
This might happen when a user account is deleted and re-added to the system.

Under rar e circumstances it was possible that the implementation triggered

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'getpwuid(): uid not found: XXXX'

This has been fixed by re-arranging the code path with an additional try/except
if the PW database information could not be retrieved leading to an implicit
chown() of the home directory to the user beeing added.
