boot-block: add option to query blocking errors

Being able to easily see if any blocking errors are present in the
system is a useful feature. A future commit will use this new interface
to tell the user if any blocking errors are present when they request a
boot of the system.

See the following design for more details:
https://github.com/openbmc/docs/blob/master/designs/fail-boot-on-hw-error.md

Tested:
- Verify blocking errors are printed
root@witherspoon:~# obmcutil bootblock
Blocking Error: /xyz/openbmc_project/logging/entry/19
Blocking Error: /xyz/openbmc_project/logging/entry/20

- Verify after resolving them, they are not printed
root@witherspoon:~# busctl set-property xyz.openbmc_project.Logging /xyz/openbmc_project/logging/entry/19 xyz.openbmc_project.Logging.Entry Resolved b 1
root@witherspoon:~# busctl set-property xyz.openbmc_project.Logging /xyz/openbmc_project/logging/entry/20 xyz.openbmc_project.Logging.Entry Resolved b 1
root@witherspoon:~# obmcutil bootblock
No blocking errors present
