[commit/testsuite] mi-language.exp: Check "langauge-option" in -list-features output.


Re: Add "language-option" to -list-features

I don't know what I hadn't thought of this before... Basically, I added
a new entry in -list-features, but never bothered to test it - mostly
because there wasn't already a test for it (IIRC!), and because the
chances of regression are most likely very small. But it seems logical
to test that entry as part of the testcase that tests the actual feature
being advertised. Done thusly:


        * mi-language.exp: Add "-list-features" test verifying that
        its output contains "language-option".

Tested on x86_64-linux.  Checked in.

PS: I recently added an entry for "ada-exceptions". But I am hoping
    to be able actually remove it, after having added the new mechanisms
    allowing a FE to check for new commands.
