mem-cache: Fix priority of multi compressor

The priority queue comparator orders such that false gives the
entry a higher priority. Therefore, if it is desired to make
the entry with lowest decompression latency have higher priority,
the comparison must be inverted.

Can be tested with:
  MultiCompressor(compressors=[
    PerfectCompressor(decompression_latency=1),
    PerfectCompressor(decompression_latency=2)])

Where it is expected that compressor0 (the one with decomp lat
of 1) is always chosen.
