system.c: reset statics for testing
this adds a function to reset the state information generated by
system_common_pre_init() for testing scenarios that need to call it
multiple times. on the EC, main memory (.data + .bss) is
reinitialized across sysjumps, so this happens automatically, but we
can't really do that from unit tests. so, add a function to reset the
relevant static variables to emulate main memory getting
reinitialized.
