ANDROID: Don't add image to all target with KBUILD_MIXED_TREE

Browse source 
When KBUILD_MIXED_TREE is set, vmlinux and related images come from an
out-of-tree location and vmlinux shouldn't be compiled. arch/arm64 and
arch/x86 add the default Images to all target, so remove that default
behavior when KBUILD_MIXED_TREE is set.

This when an out-of-tree module, e.g. virtual-device, runs "make all"
instead of "make modules".
