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.
