Recommend Inline::C, not just Inline.

Otherwise, if you have Inline but not Inline::C, you get an error like this:

    t/19-inline-c.t ............ Error. You have specified 'C' as an Inline programming language.

    I currently only know about the following languages:
        Foo, foo

    If you have installed a support module for this language, try deleting the
    config-x86_64-linux-thread-multi-5.020000 file from the following Inline DIRECTORY, and run again:

        /home/dwheeler/iov-perl/BUILD/Capture-Tiny-0.24/_Inline

    (And if that works, please file a bug report.)
