Switch to shared Spicy libraries by default.

Browse source 
This should work now. It affects only the toolchain libraries
`libhilti`/`libspicy`. the runtime libraries `libhilti-rt` and
`libspicy-rt` are always built static (but they are small). Zeek
itself doesn't link against the toolchain anymore now anyways, but a
number of the Spicy tools do.

Note, we have an issue with Broker I believe: it looks like it always
overrides BUILD_SHARED_LIBS to `OFF`

Addresses #2675.
