def kernel-flavor: linux-image-generic-lts-xenial

Ubuntu arm64: While keeping kernel 4.2 for Trusty
(linux-image-generic-lts-trusty), set 4.4 backported from Xenial
(linux-image-generic-lts-xenial) as default kernel for Armband ISO.

Xenial kernel 4.4 for Trusty has been tested with:
- AMD Softiron;
- APM Mustang;
- Cavium ThunderX;

While at it, remove obsoleted rtc-efi fixes.

Notes:
- keep 4.2 kernel inside the ISO;
- selecting 4.2 kernel may be done via deploy settings, by
  overriding kernel flavor when calling `fuel-bootstrap`;

-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.
