Rename libitm.texi Index node for case-insensitive filesystems

[Joseph S. Myers]

Various Texinfo manuals have had their indexes given node names other than 
"Index" to avoid conflicts with index.html when HTML output is generated 
and then used on a case-insensitive filesystem.  I've applied this patch 
to make such a renaming in the libitm manual, using the name Library Index 
as in the libgomp manual.  Bootstrapped with no regressions on 
x86_64-unknown-linux-gnu.
