GM9Megascript: remove "Un-install Hax" (#916)

Browse Source 
This option is confusing because despite it saying "will completely
remove CFW", it is not sufficient to actually fully remove custom
firmware. It doesn't, and can't, detect everything like region changes,
modified system titles, and other things that could brick a stock
console.

There have been numerous cases of bricked consoles because someone saw
this, thinking it would do everything needed to restore a console back
to an unmodified state, and getting a bricked console that needs a
flashcart purchase to fix.

(There is also a issue where, even if everything else was in order, it
can still brick a console due to a bad SD card. For some reason it
copies the FIRM to the SD card, where it can potentially get corrupted
if a counterfeit card was used.)

A proper uninstall guide is required, and we have one here:
