Alistair Coles 2fe18b24cd ssync: fix decoding of ts_meta when ts_data has offset 
The SsyncSender encodes object file timestamps in a compact form and
the SsyncReceiver decodes the timestamps and compares them to its
object file set.

The encoding represents the meta file timestamp as a delta from the
data file timestamp, NOT INCLUDING the data file timestamp offset.

Previously, the decoding was erroneously calculating the meta file
timestamp as the sum of the delta plus the data file timestamp
INCLUDING the offset.

For example, if the SssyncSender has object file timestamps:

  ts_data = t0_1.data
  ts_meta = t1.data

then the receiver would erroneously perceive that the sender has:

  ts_data = t0_1.data
  ts_meta = t1_1.data

As described in the referenced bug report, this erroneous decoding
could cause the SsyncReceiver to request that the SsyncSender sync an
object that is already in sync, which results in a 409 Conflict at the
receiver. The 409 causes the ssync session to terminate, and the same
process repeats on the next attempt.

Closes-Bug: #2007643
