ci: cross-build the daemon for each release target (#269)

* ci: cross-build the daemon for each release target

* ci: use Android anet linker compatibility flag

* ci: skip BSD VMs for build-only targets

* ci: FreeBSD and OpenBSD on ARM64 run the workloads in ARM64 VMs, not only build

* docs: the BSDs on ARM64 run the workloads too, and every target's daemon is built in CI

* ci: use tar sync for FreeBSD arm64 VM
