vl.c: allocate TYPE_MACHINE list once during bootup

Now all the functions used to select machine is local and the call flow
looks like below:

    select_machine()
        find_default_machine()
        machine_parse()
            find_machine()

All these related function will need a GSList for TYPE_MACHINE.
Currently we allocate this list each time we use it, while this is not
necessary to do so because we don't need to modify this.

This patch make the TYPE_MACHINE list allocation in select_machine and
pass this to its child for use.
