PR24689, string table corruption

The testcase in the PR had a e_shstrndx section of type SHT_GROUP.
hdr->contents were initialized by setup_group rather than being read
from the file, thus last byte was not zero and string dereference ran
off the end of the buffer.

PR 24689
* elfcode.h (elf_object_p): Check type of e_shstrndx section.
