build-appliance-image: upgraded VMware machine config

Build Appliance VMware configuration has
been modernized:
- Default disk is a SATA one;
- CDROM and Floppy drives removed, no real use;
- 3D acceleration not really present, removed;
This solves a warning that VMware
Player/Workstation was displaying at boot.
- IDE disk removed.
- guestOS has been set to a 64bits Linux.

Fixes [YOCTO #6680].

xserver-xorg: remove aarch64.patch

Patch aarch64.patch adds aarch64 support for xserver-xorg 1.13.1 in
header file servermd.h. And aarch64 is supported in version 1.15.1
already and the patch causes redefine error.

So remove aarch64.patch.
