ima: fix filename hint to reflect script interpreter name

When IMA was first upstreamed, the bprm filename and interp were
always the same.  Currently, the bprm->filename and bprm->interp
are the same, except for when only bprm->interp contains the
interpreter name.  So instead of using the bprm->filename as
the IMA filename hint in the measurement list, we could replace
it with bprm->interp, but this feels too fragil.

The following patch is not much better, but at least there is some
indication that sometimes we're passing the filename and other times
the interpreter name.
