Fix Kobo startup script w/ KSM
Fix Kobo startup script w/ KSM

pkill probably only checks the actual name of the binary.
We were checking a shell script, which I'm guessing is not launched
via a shebang, so that name was actually an arg to sh, or something like
that.

Use pidof instead, which matches the full command line.
