map: Proper array check for translation iteration 

The previous length check existed as a really bad array check (before
Array.isArray was a thing).  This has been broken since Nov 2012.

The problem manifests itself when you want an empty array.  We then have:
  [] => [[]] => [DEFAULT_VALUE]

* src/current/compiler/map.xsl (lvmc:compile)[lvm:map//lvm:from[*]]: Use
    `Array.isArray' in place of length check.
