Switch to libboost-headers

As we only need Boost headers in cuCIM, switch to the lighter weight
`libboost-headers` package from conda-forge. This way we only get the
headers and can skip the Boost libraries, which we don't use. Should
save some space during the build (and especially for users installing
the packages).
