LCG Local Paths Setting, master branch (2019.01.11.)

Introduced the LCG_IGNORED_SYSTEM_PATHS cache variable.

It can be used to specify which directories should be considered "system directories", and ignored while building the environment setup scripts. To allow users to specify things in addition to the previously used /usr and /usr/local directories.

I recently ran into issues with paths found by CMake that it should've really ignored in the environment setup both on MacOS Mojave and PPC64 CentOS 7. This should help with getting the analysis releases building correctly on such systems.
