Fix Makefile if statements.  They cannot be nested with spaces :(

Also only require SKY_DIR to be set if running "make run-sky-demo".
None of the other tasks depend on SKY_DIR or SKY_BUILD_DIR.

(At some point the sky_demo stuff will be removed from this repo, and
then we can drop the dependency on SKY_DIR altogether.)
