runqemu: remove setting of mem on kernel command line for certain systems

Some emulated hardware will not boot if mem is set on the kernel command
line.  Also, it is not necessary if the device tree file, as that
_should_ have the memory size specified in it.  Add a check for QB_DTB
and don't set it if specified.
