Lennart Poettering f8ecc2c00d sd-bus: make credential acquisition more graceful 
So far when asked for augmented bus credentials and the process was
already gone we'd fail fatally. Let's make this graceful instead, and
never allow augmenting fail due to PID having vanished — unless the
augmenting is the explicit and only purpose of the requested operation.

This should be safe as clients have to explicitly query the acquired
creds anyway and handle if they couldn't be acquired. Moreover we
already handle permission problems gracefully, thus clients must be
ready to deal with missing creds.

This is useful to make selinux authorization work for short-lived client
proceses. PReviously we'd augment creds to have more info to log about
(the selinux decision would not be based on augmented data however,
because that'd be unsafe), and would fail if we couldn't get it. Now,
we'll try to acquire the data, but if we cannot acquire it, we'll still
do the selinux check, except that logging will be more limited.
