There are two libraries involved: libkdu_v42R.so is the closed-source
Kadaku library that does JPEG-2000 decoding. libllkdu.so is the
Linden Labs wrapper that interfaces between that and llimagej2c.cpp.
libllkdu.so is the one you'd need to change to put the library in
resilient mode, and I suspect the reason it's closed-source is that it
contains the license key for using Kadaku.
You're probably better off modifying the OpenJPEG library to be fast
enough for practical use. I haven't managed more than about a 5%
speedup, but I haven't been trying too hard, either.
