perf python: Switch module to linking libraries from building source

setup.py was building most perf sources causing setup.py to mimic the
Makefile logic as well as flex/bison code to be stubbed out, due to
complexity building. By using libraries fewer functions are stubbed
out, the build is faster and the Makefile logic is reused which should
simplify updating. The libraries are passed through LDFLAGS to avoid
complexity in python.

Force the -fPIC flag for libbpf.a to ensure it is suitable for linking
into the perf python module.
