Avi Kivity 7d29addb1f mutation_reader: optimize make_combined_reader for the single-reader case ...

If we're given a single reader (can be common in a low-write-rate table,
where most of the data will be in a single large sstable, or in leveled
tables) then we can avoid the overhead of the combining reader by returning
the single input.

Tests: unit (release)
