Unconditionally save checkpoints when force = true
When saving update progress, we skiip a checkpoint if operation_num
isn't changed. But sometimes buffer offset changes without changing
operation num, namely, when we extract signature. If a checkpoint is
saved immediately before we extract signature, then we will skip the
checkpoint after signature is extracted, causing the on disk pref to
contain incorrect buffer_offset.
Pref causing resume failure: kPrefsUpdateStateNextDataOffset
Location on disk: /data/misc/update_engine/prefs/update-state-next-data-offset
Test: treehugger, serve an OTA update w/o slot switch then perform slot
switch
