Use dwlpp::setup_kernel for tracepoint modules.

Tracepoint modules ended up going through dwflpp::setup_user() because
there was no setup_kernel that takes a list of module names.

* dwflpp.h: Add kernel_p bool to constructor that takes a module list.
  Add setup_kernel() variant that takes a module list.
* dwflpp.cxx: Likewise.
* tapsets.cxx (tracepoint_builder::init_dw): Call dwflpp constructor
  indicating we expect kernel modules.
