compiler-clang: remove version check for BPF Tracing
bpftrace parses the kernel headers and uses Clang under the hood.
Remove the version check when __BPF_TRACING__ is defined (as bpftrace
does) so that this tool can continue to parse kernel headers, even with
older clang sources.
Fixes: commit 1f7a44f63e6c ("compiler-clang: add build check for clang 10.0.1")
