bisync: isDir check for deltas

Browse Source 
Before this change, if --create-empty-src-dirs was specified, bisync would
include directories in the list of deltas to evaluate by their modtime,
relative to the prior sync. This was unnecessary, as rclone does not yet
support setting modtime for directories.

After this change, we skip directories when comparing modtimes. (In other
words, we care only if a directory is created or deleted, not whether it is
newer or older.)
