[CMake] Define SHOULD_INSTALL_JS_SHELL before including ports Options files.

Reviewed by Martin Robinson.

* CMakeLists.txt: If OPTION() is called after Options${PORT}.cmake is included, it will
override whatever value a port may have set for it. The GTK+ port, for example, tries to set
it to SHOULD_INSTALL_JS_SHELL to ON by default, even though it did not happen before.
