Subject: CMakeLists.txt: Avoid host-specific path to libsodium

Avoid propagating full build host specific path to generated
ZeroMQTargets.cmake when building with libsodium, which changes the
content in generated ZeroMQTargets.cmake files followingly:

  -INTERFACE_LINK_LIBRARIES "-lpthread;/build/host/specific/path/to/zeromq/4.3.2-r0/recipe-sysroot/usr/lib/libsodium.so;-lrt"
  +INTERFACE_LINK_LIBRARIES "-lpthread;-lsodium;-lrt"

This change mitigates an issue stemming from reuse of build artifacts
where the path to libsodium.so does not match exactly between two
different build hosts.
