TerminalLogger overwrites "attempting to cancel the build" message

[rainersigwald]

When you cancel command-line MSBuild, we send the cancellation signal through the API and also writes status to stdout. But it does so directly:

msbuild/src/MSBuild/XMake.cs

Line 1007 in 39e20dc

Console.WriteLine(ResourceUtilities.GetResourceString("AbortingBuild"));

And terminallogger tends to immediately overwrite that message with status updates, so it's not obvious whether cancellation is in progress.
