The systemtap tool, when executed, searches for the vmlinux image in /boot/.
The currently shipped vmlinux image in Debian is with the -dbg package that
installs it into /usr/lib/debug.
Could you please handle a symlink to /boot for vmlinux ?
This is required for systemtap. I have manually verified it by creating
the symlink and it works.
Without it, following error is seen:

No, this is a bug in systemtap. I will reassign this bug.
