qemux86-directdisk: remove mem= parameter
Remove usage of a specific amount of memory and let it be controlled by
users. This was the default behaviour before it was changed by commit
3b79d9a78 that switched the wks file to be used for qemux86.
Also fixes the bitbake parsing issues seen because of memory starvation
using build appliance images.
Fixes [YOCTO #12894]
