Add OpenCV without CUDA.

This is OpenCV for the ictce 5.5.0 toolchain without CUDA. One of the challenges we've had is to make sure we have all the deps taken care of. Running `ldd` on the binaries in the installed directories and filtering out EasyBuild dependencies results in the following:
```
-bash-4.1$ ldd ~/.local/easybuild/software/OpenCV/2.4.8-ictce-5.5.0/bin/* | grep -v `whoami`| grep -v sandy | sort  | awk '{print $1}' | uniq
/lib64/ld-linux-x86-64.so.2
libc.so.6
libdl.so.2
libgcc_s.so.1
libglib-2.0.so.0
libgthread-2.0.so.0
libm.so.6
libpthread.so.0
librt.so.1
/$LIB/snoopy.so
libstdc++.so.6
linux-vdso.so.1
```

This required libjpeg (for which I've used libjpeg-turbo) and thus a toolchain version of NASM.
