Set CHPL_LLVM=none for gen_release

[reviewed by @daviditen]

gen_release is the script we use to create our tarball. As part of that
it builds the documentation, which requires chpldoc, which depends on
our compiler. When building the docs set CHPL_LLVM=none since we don't
need llvm just to run chpldoc.
