The clang bpf cmdline template has defined default value in the file
tools/perf/util/llvm-utils.c, which has been changed for several times.
This patch updates the documentation to reflect the latest default value
for the configuration llvm.clang-bpf-cmd-template.
Fixes: d35b168c3dcd ("perf bpf: Give precedence to bpf header dir")
Fixes: cb76371441d0 ("perf llvm: Allow passing options to llc in addition to clang")
Fixes: 1b16fffa389d ("perf llvm-utils: Add bpf include path to clang command line")
