size: Fix corner case with multiple items on the command line. 

Fixes 'guix size foo bar' when 'foo' is in the local store and 'bar'
isn't, which could lead to an incomplete requisite list.

* guix/scripts/size.scm (requisites*): Partition ITEMS according to
'valid-path?'.  Use 'substitutable-requisites' only on invalid items.
