Bug 1416062 - xpidl/ipdl/webidl outputs should be in the installed-files group for tup; r=chmanchester

Since these processes generate header files that will be used for
compilation, they should output to the installed-files group. We can use
the installed-idls group to separate installing things into dist/idl
from the actual XPIDL processing.
