Have load-in-vicinity' look for .go' files in %LOAD-COMPILED-PATH.

Fixes <http://bugs.gnu.org/12519>.

* module/ice-9/boot-9.scm (load-in-vicinity)[fresh-compiled-file-name]:
  New `scmstat' parameter; use it.
  [sans-extension]: New procedure.
  [load-absolute]: Call (stat ABS-PATH) from here.  Search a `.go' file
  from %LOAD-COMPILED-PATH before searching %COMPILE-FALLBACK-PATH.
