libelf: gelf_getphdr should check phdr index is valid. elf_getphdrnum does checks the phdrnum makes sense. But gelf_getphdr checked the given index against the "raw" e_phnum or internal __elf_getphdrnum_rdlock result without checking. Extract the checking code into a new internal __elf_getphdrnum_chk_rdlock function and use that. Found by afl-fuzz. Signed-off-by: Mark Wielaard <mjw@redhat.com>
