Control the frequency of fileBrowserPrivate.onFileTransfersUpdated events.

Control the frequency of fileBrowserPrivate.onFileTransfersUpdated events.

The update notifications were sent at every download progress and flooded the
file manager UI. This patch inserts a check on frequency so that the event
keeps the interval of certain (currently 1000) milliseconds.

BUG=138838
TEST=manually tested copying large files.
