RFR: 8256489: Make gtest for long path names on Windows more resilient in the presence of virus scanners

[Ralf Schmelter]

Hi,

a virus scanner can keep a file open on Windows, so that a DeleteFile command returns successful, but the file is actually not removed when the call returns. In the gtest for long path names on Windows this can lead to failures when a directory is tried to be removed, but the file inside it is still kept by the virus scanner.

Since this is an error which only occurs very infrequently, we just retry the deletion a few times. 

Best regards,
Ralf
