set-program-arguments from scheme

[Kevin Ryde]

How about making scm_set_program_arguments() available at the scheme
level too?  As say

        (set-program-arguments lst)

(without the "first" arg business of the C level).

The C func is good for when you munch some options at the C level in
an scm_boot_guile, having it at the scheme level would be for the same
thing if do it in scheme instead.
