Subject: [PATCH 1/1] BaseTools/GenFds: Change FV Header to FileSystemGuid3.

Following PI spec: when there has Ffs with EFI_FFS_FILE_HEADER2, the Parent Fv of the Ffs need set to FileSystemGuid3; when all the Ffs with EFI_FFS_FILE_HEADER, the Parent Fv of the Ffs need set to FileSystemGuid2.
Currently, when changing the Ffs in Fv from EFI_FFS_FILE_HEADER to EFI_FFS_FILE_HEADER2, the Fv FileSystemGuid does not changed consistent with Ffs type.That caused build issue.

This patch fixes this issue.
As FileSystemGuid3 is compatible with FileSystemGuid2, change all the Fv header to FileSystemGuid3.
