set fallback drivers to avoid updating pci-id lists

[Timo Aaltonen]

[Impact]
The AMD/Intel pci-id's keep changing when new platforms are enabled. Currently, the new ones need to be added to the kernel, libdrm, mesa and xorg-server. This duplication is silly, as there's a limited number of drivers for a platform, so use a default (fallback) DRI driver for a vendor. For Intel it's i965, for AMD it's radeonsi.

[Test case]
check that the correct driver is still used on an Xorg session and DRI works

[Regression potential]
shouldn't be any

the hwe stack update from eoan can and should override this SRU at this point..

[Łukasz Zemczak (sil2100)]

This has been overriden by the 2:1.20.5+git20191008-0ubuntu1~18.04.1 hwe stack update SRU.

[Timo Aaltonen (tjaalton)]

since the hwe stack update works on intel/amd, this bug is verified
