KItemListKeyboardSearchManager: make it possible to choose the timeout

It's now possible to change the timeout, after which any call of
KItemListKeyboardSearchManager::addKeys(const QString&) starts a new
search, from the default value of 5000 milliseconds. This is not used
in Dolphin at the moment, but it permits to reduce the timeout to a
small value in the unit test. Before this change, the unit test took
more than 5 seconds to complete.
