Håkan Kvist b77972402e Detect downgrade by checking build time for all partitions 
Checking ro.build.date.utc to detect a downgrade is not enough in the
case where several target files are merged, as timestamps can differ
for each partition.

The solution is to check the build timestamp for each partition and
ro.build.date.utc.

With this change ota generation will be aborted during creation
instead of rejected when installing on device.

This also fixes the --override_timestamp so it is possible to generate
a package where timestamps are reversed, as was added in:
3e6161a3b3.

Issue: 315913966
Test: Manual, confirm that ota generation is aborted when timestamp
  on post vendor partitions is newer than on pre.
  Ota created successfully with --override_timestamp parameter and
  installation successful
Test: atest --host releasetools_test
