libdw: check that DWARF strings are null-terminated
It is expected from libdw to return strings that are null-terminated to
avoid overflowing ELF data.
* Add calculation of a safe prefix inside string sections, where any
string will be null-terminated.
* Check if offset overflows the safe prefix in dwarf_formstring.
