Display error message for missing ".BTF" section and clean up empty
vmlinux.h file.

v3:
- fix typo and make error message consistent. (Andrii Nakryiko)
- split out perf change.
v2:
- remove vmlinux specific error info.
- use builtin target .DELETE_ON_ERROR: to delete empty vmlinux.h

Changbin Du (2):
libbpf: show error info about missing ".BTF" section
bpf: makefiles: do not generate empty vmlinux.h
