Subject: [PATCH] src/dso.c: use ehdr.e_shstrndx as index
According to struct elf32_hd, the e_shnum is section header number, and the
index is e_shstrndx, not e_shnum.
This can fix segmention fault when handle libqb.so.0.18.2 from libqb_1.0.3.
It fails to handle libqb.so.0.18.2 and get errors:
Symbol section index outside of section numbers
Then segmentation fault, this is because the e_shnum is 34, while e_shstrndx is
27 (it would be 33 when no errors), I've checked several elf files to confirm
that the ones after e_shstrndx is NULL, so use e_shstrndx should be correct.
