Build LSAN suppressions into the test binaries.

This way you don't need to set LSAN_SUPPRESSIONS in your environment...
sort of foolproof this way.

I _think_ the strdup() business from skia:2916 is actually rooted in
libfontconfig, so one suppression should cover both old ones.

I'll leave the file empty until I clean up mention of it in bot recipes.
