Leaktest: disable support for following target/targetname by default.
Instead, mark any entities created during initialization as non-leaky.
This should solve everything that the targetname support was meant to
solve (namely info_notnull entities), but is more general (e.g. would
also work with Xonotic's killtarget/target2/target3/target4 and
target0/name of Doom 3).
