[PATCH 5/5] systemd: add RRECOMMENDS for weak dependencies, if enabled

["Luca Bocassi" <luca.boccassi@gmail.com>]

From: Luca Boccassi <luca.boccassi@microsoft.com>

Some libraries are now dlopen'ed and skipped at runtime if
not available. Add them to the RRECOMMENDS list, to allow
users to exclude them for smaller images even if generally
enabled at build time.
