environment: Use 'evaluate-search-paths'. 

This allows 'guix environment' to correctly handle non-directory
and/or pattern search-path specifications, such as that for
'XML_CATALOG_FILES'.

* guix/scripts/environment.scm (for-each-search-path): Use
  'evaluate-search-paths' instead of 'search-path-as-list' & co.
