CI: Use larger timeout multiplier for ASan tests

Running under ASan introduces a good amount of overhead. Using the Meson
test wrapper rather than invoking a Ninja target lets us set a timeout
multiplier, which we smash up pretty high to account for this overhead
and prevent some of the larger tests from hitting timeout.
