libbpf: Verify section type in btf_find_elf_sections
A valid ELF file may contain a SHT_NOBITS .BTF section. This case is
not handled correctly in btf_parse_elf, which leads to a segfault.
Before attempting to load BTF section data, check that the section
type is SHT_PROGBITS, which is the expected type for BTF data. Fail
with an error if the type is different.
