inteltool: clean up file descriptors a bit

Paul Menzel reported that Cppcheck 1.59 reported an unused variable io_fd.
    While that is true, the underlying issue is that the file descriptors are not
    closed properly at the end. "a bit" referes to the numerous exit calls all
    around that of course circumvent the cleanup.

Arguably one could live without cleaning up because it is done automatically
    anyway.
