machine: use class base init generated name

Browse Source 
machine_class_base_init() member name is allocated by
machine_class_base_init(), but not freed by
machine_class_finalize().  Simply freeing there doesn't work,
because DEFINE_PC_MACHINE() overwrites it with a literal string.

Fix DEFINE_PC_MACHINE() not to overwrite it, and add the missing
free to machine_class_finalize().
