[core] work around a Windows bug where GetVolumePathNamesForVolumeName() can return the wrong drive letter 
* A user is reporting that, on one of their platforms, Rufus is writing to the wrong target during the file-copy
  phase and using their existing Y: local drive instead of the drive associated to the USB, despite the fact
  that Rufus is passing the right volume name to GetVolumePathNamesForVolumeName().

* Here's the PowerShell wmic output, confirming that the volume GUID obtained by Rufus is the right one:

  DriveLetter : Y:
  DeviceId    : \\?\Volume{000349b1-17d0-69f6-c13f-f31162930600}\
  Capacity    : 118540464128
  FileSystem  : NTFS
  Label       : Y-DISK

  DriveLetter : H:
  DeviceId    : \\?\Volume{b150ff4a-d62b-11ea-86e3-f49634660e54}\
  Capacity    : 15791824896
  FileSystem  : FAT32
  Label       : ADATA16GB

* And here's the Rufus log demonstrating that GetVolumePathNamesForVolumeName() is returning the *WRONG* letter:

  Found volume \\?\Volume{b150ff4a-d62b-11ea-86e3-f49634660e54}\
  \\?\Volume{b150ff4a-d62b-11ea-86e3-f49634660e54}\ is already mounted as Y: instead of H: - Will now use this target instead...

* The last line shows, without the shadow of a doubt, that we did feed "\\?\Volume{b150ff4a-d62b-11ea-86e3-f49634660e54}\" to
  GetVolumePathNamesForVolumeName() and that this API call was successful (returned a non zero size) but ultimately returned
  the wrong letter (Y: instead of H:)...

* Therefore, Windows is BUGGY and the use of GetVolumePathNamesForVolumeName() must be avoided.
