This reverts commit 346cd79192. The bug
report was incorrect, since the suggested file name is actually valid,
it just happens to name an Alternate Data Stream (ADS) "20:803Z.txt" in
file "testLog-03".
[ChangeLog][QtCore][QFile] Reverted an incorrect change from Qt 5.9.0
that forbade the creation and access to Alternate Data Streams on NTFS
on Windows. This means that file names containing a colon (':') are
allowed again, but note that they are not regular files.
Task-number: QTBUG-57023
