Subject: [PATCH] libsystemd: link with '-z nodelete'

We want to avoid reinitialization of our global variables with static
storage duration in case we get dlopened multiple times by the same
application. This will avoid potential resource leaks that could have
happened otherwise (e.g. leaking journal socket fd).
