OK, I've never run systemtap on Android, so I won't be much help there.
As far as DebugFS being required, the flag you are looking for is
CONFIG_DEBUG_FS.

As far as running systemtap on Android, have you looked at the following
link?

<https://sourceware.org/systemtap/wiki/SystemTapOnAndroidARM>

It was updated fairly recently.
