[3.9] Multiple jumpstart scripts are created

[Informatic]

HE_DTV_W17R_AFAAABAA, 06.00.10 Software Version.

Summary of a saga from: https://github.com/webosbrew/youtube-webos/issues/30

Somehow "legacy" (v1) jumpstart script write errored out, while still writing a file properly, leaving a system with multiple jumpstarts, causing Failsafe Mode popup to show up on every boot.

at least for me there’s only one jumpstart script, but it gets executed twice:

A fix/workaround for this has been released in Homebrew Channel v0.5.0 - this will be set as a default installed version ~this weekend, after we confirm no issues with that version..
