a9c391b9e3 Remove the 'payload' stuff now that we're just doing IO. 
This unifies the android and other-linux code paths.

The rationale for just doing IO now is as in the previous commit:
we need the whole process to be run as root, so we don't need to
isolate this particular IO in a separate `su -c` command anymore.

ff6537abff Make sampling work on current Android (no su -c). 
The `su -c` approach does not work on current Android. It seems that
on current Android, access to /proc and /sys is restricted enough
that in practice, developers profiling on Android are likely running
the whole instrumented process as root anyway, so `su` shouldn't be
needed. (In particular, note that access to /proc/$pid is limited
to members of a `readproc` group).
