make mem_path local variable

Browse Source 
It's no longer used anywhere beside main(),
so make it local variable that is used for CLI compat
purposes to keep -mem-path option working.

Under hood QEMU will use it to create
  memory-backend-file,mem-path=...
backend and use its MemoryRegion as main RAM.
