Mathieu Duponchelle ae7a213628 valgrind suppressions: ignore XInitThreads leaks
As we load that symbol dynamically, valgrind gets confused
when it leaks and reports the leak against an unrelated library
and an unknown (??) symbol.

To address that, put the loading and calling of that symbol
in a separate function, and ignore any malloc leak happening
in that function.
