UX: Fix: rtc-efi blacklist for Ubuntu targets.

Previously, rtc-efi module was blacklisted in fuel-library preseed
cobbler template, which is not used for Ubuntu target nodes.

Fix by instead blacklisting rtc-efi in cloud-init jinja2 template.

+Subject: [PATCH] target Ubuntu: Blacklist rtc-efi if not supported.
+
+Older ThunderX and possibly other UEFI-enabled targets do not support
+rtc-efi properly, so they end up filling dmesg with useless
+complaints about not being able to read system time.
+
+Target OS (Ubuntu) deployment already has a snippet that blacklists
+i2c_piix4 in certain scenarios, so provide a similar test for rtc_efi.
