A Request to Add MiThoriumSSI support

[neogen6]

my local manifest for lineage-20.0: https://github.com/neogen6/local_manifests/blob/lineage-20.0/lineage-20.0.xml

upstream local manifest: https://github.com/Mi-Thorium/local_manifests

example build: https://cirrus-ci.com/build/5542712833736704

Closest thing I could find is this comment: #9810 (reply in thread)

Use 1 space at lunch line after lunch command, your script has 2 spaces.
