libipt, time: fix TMA handling for low MTC frequencies
When the MTC frequency is low, TMA does not provide the full CTC value. We
estimate a CTC value based on the TMA's CTC field size.
The current version assumes that TMA does not provide any bits in the MTC range.
This is wrong. The TMA may provide some but not all bits that an MTC would
provide.
Generalize it by filling in the missing bits when processing the next MTC. This
assumes that we're not dropping MTC packets around TMA. At least not more than
TMA provides bits for.
