Example: remove map example
This example only demonstrates the use of blockingMapped. Considering
that the QtConcurrent::mapped~ functions are already included in the
wordcount example, and have very similar APIs to the
QtConcurrent::filter~ functions, which are included in the
progressdialog example, this no longer serves a useful purpose.
Task-number: QTBUG-111165
