Bug#1029167: mozjs78: Fails to build on armhf and armel

[Joshua Peisach]

CJS ported to mozjs78 in October 2020, and Cinnamon is still finishing their 5.6x releases/making cleanups.

Considering upstream uses Ubuntu Jammy, mozjs102 isn’t an option unless they are willing to build it for their main development target. I think Cjs should rebase for mozjs91,
Especially if mozjs78 is EOL.
