classes/sstate: show progress during sstate object availability check

Show progress through bitbake's standard terminal UI when checking for
shared state object availability, since this can take some time if there
are a large number of tasks to be executed and/or the network connection
is slow.

Part of the implementation for [YOCTO #5853].
