Azure windows machines require cleardown

[M-Davies]

While working on testing some code changes for an issue I am working on, I enabled clean workspace for some builds by accident which has reproduced #1396. They will likely need to be cleaned out before the nightly builds start later

For the file on azure-1 it cannot remove a zero lenght file called _the.. in the directory that it's having problems with. I'v retried from the command line and also from the GUI - no change. The machine wants to reboot itself for updates anyway so I'll initiate that just now which should clear it out

Seems to be the same file on -2:

j:\jenkins\tmp\workspace\build\src\build\windows-x86_64-normal-server-release\jdk\gensrc\java\nio\_the..

The file was created at exactly 8am today UK time. I'll reboot it too

That didn't work ... However removing it with the cygwin rm command did ... Closing, but rather confused ...

So, this PR seems to have fixed this problem for specifically the path: C:/workspace/openjdk-build/workspace/build/src/build/*/jdk/gensrc (as that was the path that was affecting Softlayer machines). It seems an additional context.sh script or more general fix is required to fix it for the azure machines. Not sure why it's only now it decided to start being an issue with azure.

@Willsparker Can you raise a build issue for that?
