bootstrap: Add 'armband-rtc-efi-fix' package

bootstrap: Add 'armband-rtc-efi-fix' package

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.

armband-rtc-efi-fix validates rtc-efi can be used on the system,
otherwise it rmmods rtc_efi kernel module via rcS script.

This patch hardcodes the addition of armband-rtc-ef-fix package during
bootstrap image build.

NOTES:
This could be later removed or, if other fixes need to be delivered
like this, grouped in a meta package.

Target OS (Ubuntu) still needs to be handled, preferably by blacklisting
rtc-efi module and rebuilding initramfs during provisioning.

Fuel 9.0 moved default package list to openstack.yaml fixture, see [1].
