Tweak to initial heap size selection

Browse source 
* libguile/gc.c (DEFAULT_INITIAL_HEAP_SIZE): Bump a bit farther (2 MB on
  64-bit, 1 MB on 32-bit) as we now expand to this size instead of
  expanding by this amount.
  (scm_storage_prehistory): Expand to the initial heap size instead of
  expanding by the size.
