[zeromq] prevent using hosts libbsd when cross compiling

[jbbjarnason]

Solves the issue:
If the host has libbsd installed and you try to cross compile for aarch64 for example, the WITH_LIBBSD gets activated and fails to compile since it is non existing in aarch64 system root.

Default turning WITH_LIBBSD to OFF when vcpkg is configured to cross compile.

• Changes comply with the maintainer guide
• SHA512s are updated for each updated download
• The "supports" clause reflects platforms that may be fixed by this new version
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.
