WinCE: Remove QIncrementalSleepTimer from QProcess::waitForFinished

Remove a superfluous loop and thus the usage of QIncrementalSleepTimer
from QProcess::waitForFinished. We just wait for the process handle.
There's no need for a loop that checks multiple wait conditions.
This enables us to remove QWindowsPipeWriter from the Windows CE port in
a subsequent commit.
