libbpf: Support raw BTF placed in the default search path
Currently, the default vmlinux files at '/boot/vmlinux-*',
'/lib/modules/*/vmlinux-*' etc. are parsed with 'btf__parse_elf()' to
extract BTF. It is possible that these files are actually raw BTF files
similar to /sys/kernel/btf/vmlinux. So parse these files with
'btf__parse' which tries both raw format and ELF format.
This might be useful in some scenarios where users put their custom BTF
into known locations and don't want to specify btf_custom_path option.
