Update to Oracle version 6.1.14a.

This minor update enables the building of libvirt again.

Version update to 6.1.14 (released September 04 2020 by Oracle)

File "fix_virtio_build.patch" is added to fix a build problem.
This is a maintenance release. The following items were fixed and/or added:
GUI: Fixes file name changes in the File location field when creating Virtual Hard Disk (bug #19286)
VMM: Fixed running VMs which failed to start with VERR_NEM_MISSING_KERNEL_API_2 when Hyper-V is used (bug #19779 and #19804)
Audio: fix regression in HDA emulation introduced in 6.1.0
Shared Clipboard: Fixed a potential crash when copying HTML data (6.1.2 regression; bug #19226)
Linux host and guest: Linux kernel version 5.8 support
EFI: Fixed reading ISO9660 filesystems on attached media (6.1.0 regression; bug #19682)
EFI: Support booting from drives attached to the LsiLogic SCSI and SAS controller emulations

Pseudo version bump to 6.1.13, which is NOT an Oracle release.

Update VB sources to run under kernel 5.8.0+ with no modifications to the
kernel. These sources are derived from r85883 of the Oracle svn repository.
For operations with USB{2,3}, the extension pack for revision 140056 must
be installed. Once Oracle releases 6.1.14, then the extension pack and
VB itself will have the same revision number.
File "fixes_for_5.8.patch" is removed as that part was fixed upstream.
Fixes boo#1175201.

Apply Oracle changes for kernel 5.8.
