Title: small fixes to build with system libraries

a couple fixes to build cvmfs from sources with system libraries (packaging for gentoo distro):
- tracer.cc was including a generated file config.h which is not generated while using the *_BUILTIN=OFF
- find_package(leveldb) was assuming a Findleveldb.cmake module not available. this module is a slight modification from another project.
