module: Additional validation in elf_validity_cache_strtab
Validate properties of the strtab that are depended on elsewhere, but
were previously unchecked:
* String table nonempty (offset 0 is valid)
* String table has a leading NUL (offset 0 corresponds to "")
* String table is NUL terminated (strfoo functions won't run out of the
table while reading).
* All symbols names are inbounds of the string table.
