perf build: Remove libbpf pre-1.0 feature tests 



The feature tests were necessary for libbpf pre-1.0, but as the libbpf
implies at least 1.0 we can remove these now.

Committer notes:

Modified tools/perf/Makefile.config to better reflect the reason for
failure when the libbpf present is < 1.0 and LIBBPF_DYNAMIC=1 was asked
for.
