What's wrong with using input-file-name ?  This should work for the main
input file.  If you need more than that, you can likely work with
something like

#(read-hash-extend #\< (lambda (c p) (port-filename p)))

#(display #<)

This will not work before 2.15.twentyish (when I decided that the
terrible error messages for Scheme code were not doing anybody a favor,
and made port-filename, port-line, and port-column point to sensible
locations).
