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.

This adds a simple test for rtc-efi and blacklists it in target OS
(Ubuntu) if not supported.

While we're at it, rename a patch file I missed in a previous rebase
and update TODO.

+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.
+
+update-initramfs is already invoked from i2c_piix4 snippet, so ommit
+explicitly calling it in rtc_efi fragment.
