btf: rename /sys/kernel/btf/kernel into /sys/kernel/btf/vmlinux
Expose kernel's BTF under the name vmlinux to be more uniform with using kernel module names as file names in the future. Fixes: 341dfcf8d78e ("btf: expose BTF info through sysfs") Suggested-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
