Need to re-enable generation of LICENSE files

[fmarier]

Test plan

Likely steps a developer will need to do 😄

1. Queue build of 1.7
2. Ensure builds succeed
3. Verify that license generation portion of build (on each platform) was done during create_dist
4. Mark issue as verified!

Description

#8616 temporarily disabled license generation in order to fix a build failure (#8615).

We need to make sure it's re-enabled (likely by #8560) since we can't ship 1.7 without it.

Added some steps we can try when queueing the next 1.7 build 😄
