Set Makefile config variables for libbpf

Browse source 
Source files modified:

* Makefile.config - Checks whether libbpf is installed on the system.
If so, we add -lbpf to LIBS_FEATURES, -DCONFIG_HAS_LIBBPF to
FEATURE_DEFINES and set CONFIG_HAS_LIBBPF. This allows us to check for
the presence of libbpf before compiling or executing BPF c/r code and
ZDTM tests.

* Makefile - Set CONFIG_HAS_LIBBPF to clean all files.
