CMakeLists.txt: OSG_FIND_3RD_PARTY_DEPS option

Browse Source 
Android-specific macros aren't needed in some cases, e.g. if the NDK is
setup with all the needed dependencies a much easier way to find
packages is to simply specify the correct `CMAKE_FIND_ROOT_PATH`.

The `ANDROID_3RD_PARTY` macro interferes with this.
Adds an option to disable it.

WIN32 build is in a similar situation, the new option affects it also.
