Fix EIGENSPARSE option help s/t it displays in CMake ncurses GUI.
- Shorten description for EIGENSPARSE to a single line, as otherwise
it is not correctly displayed in the ncurses CMake GUI.
- Made explicit in description that this results in an LGPL licensed
version of Ceres (this is also made clear in the CMake log output if
EIGENSPARSE is enabled).
