amdfwtool: Remove the function's dependency to ctx

This is for next CL to move the write_body to another source,
handle_file.c.
https://review.coreboot.org/c/coreboot/+/78305

Removing amdfwtool_cleanup in write_body will not change the
result. Write_body returns to main and amdfwtool_cleanup still ends up
getting called.
