Subject: [PATCH] Enable ccache-backed Spicy JIT for users of developer
 scripts.

For CI and more general BTest execution we already enabled ccache
previously, but developers using a Spicy build out of the build
directory still needed to manually set up caching.

With this patch we enable it for such cases as well via
`zeek-path-dev.*sh`.
