The current implementation of wildcardToRegularExpression doesn't
anchor the pattern which makes it not narrow enough for globbing
patterns. This patch fixes that by applying anchoredPattern before
returning the wildcard pattern.
[ChangeLog][QtCore][QRegularExpression] The wildcardToRegularExpression
method now returns a properly anchored pattern.
