csync_reconcile: Optimize reconcile by avoiding alocations

Fix performence regression from commit d66c2b5faecc689c52df23d7dbc44c894b92febc
For every new file we would look up every parent directories. Allocating
a new QByteArreay for every parent riectory just to know if it is in the other
tree is wasting lots of CPU.
Use a ByteArrayRef trick, similar to QStringRef
