Subject: [PATCH] build: cmake: set more properties to alternator library

alternator headers are exposed to the target which links against it,
so let's expose them using the `target_include_directories()`.
also, `alternator` uses Seastar library and uses xxHash indirectly.
we should fix the latter by exposing the included header instead,
but for now, let's just link alternator directly to xxHash.
