sstate: Add check_for_interrupts() call functionality added in bitbake

Add in the new 'check' calls which mean that the code can exit from longer
running code loops if requested by the user. This covers sstate checks and
sstate manifest cleanup code which currently couldn't be interrupted by the
user from the UI.

Increase the minimum bitbake version which brings in this API.
