command-line-tool: Do not embed stdout-filename outside main body.

stdout-output->value cannot access the inputs variable, and thus
will fail when stdout-filename is a parameter reference that needs to
be evaluated. To avoid this, pass it in as an argument.

*
ravanan/command-line-tool.scm (build-command-line-tool-script)[stdout-output->value]:
Accept stdout-filename as argument instead of G-expression embedding.
Pass stdout-filename as argument to stdout-output->value.
