[cmake] Check for the presence of the the daemon library call

Summary: daemon is only defined on some plateform and checked in the codebase using a define in the configuration. This ensures that cmake produces the proper define in its configuration.

Test Plan:
Build with cmake/ninja

./src/bitcoind -daemon
tail -f ~/.bitcoin/debug.log

Ensures that the node catches up with the chain as expected.
