[PATCH] Fix punctuation handling in the ibmtts module.

[Christopher Brannon]

We were sending the wrong value for the punctuation mode when the
user selected "all punctuation" or "some punctuation".
Now, we send the correct value in all cases.

Also, the function is simplified slightly, as g_malloc + snprintf is
replaced with a single call to g_strdup_printf.
