tune default hash table sizes

Browse source 
* libguile/modules.c: In my current image, there are 1790 bindings in
  the root module, which tips over to the next hash vector size, so
  declare that to prevent rehashing.
* libguile/srcprop.c (scm_init_srcprop): Don't preallocate a big
  source_whash table, as we might not need it (if everything is
  compiled, for example).
* module/ice-9/boot-9.scm (make-module): Don't preall-cate big hash
  tables for imported bindings.  Instead trust that resizing works
  correctly.
