  When calculating arguments to the interpreter for the shebang script
  executed by fexecve(2), imgp->args->fname is NULL. Moreover, there is
  no way to recover the path to the script being executed.
  Do what some other U*ixes do unconditionally, namely supply /dev/fd/n
  as the script path when called from fexecve(). Document requirement of
  having fdescfs mounted as caveat.
