inject.sh: use subshell to speed up find_me()

the current test allows a further extraction after
running mecleaner, even if me.bin was found.

further, any recursive calls that exit non-ze
don't lot the loop acthually stop, unless we
subshell that too, otherwise fx_ is returned to
return 0 when a given command it runs returns 1,
or more specifically: the for loop in x_ breaks.

this is by design, and there's not much that can
be done, but this patch should pseed up extraction
a little bit, when dealing with intel me files.
