[BUG-4357] Alpha masking is broken again on avatar clothing when ALM is enabled.

[sl-service-account]

It's baaaaack!

Steps To Reproduce

1. Wear a mod shape and edit the eyelashes to have max length & save shape changes.
2. Create a new system skirt and wear it.
3. Stand avatar against a large prim and set transparency on the prim >0

4. Observe how skirt and eyelashes look when viewed with the prim behind your avatar with ALM enabled and with ALM disabled.

   Observed Behaviour

• With ALM enabled, the hidden parts of the eyelashes and skirt will display the scene behind the prim - see Fig 1 & Fig 3.

• With ALM disabled, the skirt and eyelashes render correctly - See Fig 2 & Fig 4.

  Expected Behaviour

  The behaviour when ALM is disabled is the correct behaviour.
