Rework submodule installation (#70)

* Rework submodule installation

- use add_subdirectory(... EXCLUDE_FROM_ALL) + explicit installation of deps
- install all library deps to lib/omnitrace
- internal builds of dyninst use libomnitrace-rt for binary rewriting
- support libdyninstAPI_RT not in LD_LIBRARY_PATH when dyninst built internally

* Update ubuntu-focal to test full dyninst install

* Use RelWithDebInfo because Dyninst segfaults with MinSizeRel

* Fix ubuntu-focal.yml install step
