drgn: add new recipe

drgn is a debugger with an emphasis on programmability
drgn exposes the types and variables in a program
for easy, expressive scripting in Python.

Drgn depends on:
1. python3
2. elfutils
3. openmp
a. clang toolchain should use libomp(openmp)
   from meta-clang
b. gnu gcc toolchain should use libgomp(gcc-runtime)
   from openembedded-core

The build requires:
1. setuptools
2. automake
3. autoconf
4. libtool
5. pkgconf
