snapuserd: Update verification
Initiate update verification from daemon. This will help
in two ways:
1: We avoid reading everything into page-cache. Since,
low end devices are already short on memory, we don't
want to read and populate page-cache which can slow
down boot.
2: During boot, once the selinux transition is done, daemon
is all ready to kick off the verification since verity is
already setup. Note that we are still guarded by update_verifier.
Update_verifier will still block marking new slot as
boot success until the verification is completed. So, there
is no change in the behavior.
