Saddled Pigs and Striders don't drop saddle with doMobLoot=false

Summary:
Saddled Pigs and Striders don't drop saddle with doMobLoot=false.
Because horses, mules and donkeys drop saddles when doMobLoot=false, as well MC-15114 is WAI (dropping saddles is an intentional feature), the expected behavior is that pigs and striders will drop saddles. The Java edition had a similar issue with pig MC-92772.

Steps to reproduce:

1. /gamerule doMobLoot false
2. Summon a pig and a strider.
3. Equip them with a saddle.
4. Kill them.

Observed results:
The pig and the strider did not drop their saddle.

Expected results:
Saddles will drop from the pig and the strider.
