Add aarch64 support to beaker.

- Allow distro import to recognise Red Hat Server distro as a RHEL distro
- write out aarch64/grubefi entries.  Unfortantely its different enough from efigrub.
  - need to pass machine specific dtb file, but this will go away RSN.
  - each host needs a filename entry in dhcpd.conf.  grub/efi won't fall through once grub.efi is
    loaded from tftpboot.  The only way around it seems to remove the entry.
- Update kickstart.py to put %end for new osmajor

do not use sh-style quoting for kernel options

Although Anaconda parses /proc/cmdline using shlex.split, the kernel
itself defines its command line in bootparam(7) as space-separated
tokens with no quoting or escaping. Dracut follows this lead and
parses /proc/cmdline as space-separated tokens with no quoting.

In practice no kernel options ever need to contain spaces or shell
metachars so there is no effective difference. The one corner case we
know of is URLs containing the tilde character, which pipes.quote
considers to need quoting.

don't truncate watchdog time remaining to 7 characters

The '%.7s' format string had the effect of truncating off the
microsecond portion of the time remaining, however it failed to deal
with timedeltas outside the range of (0, 10 hours].

This patch avoids a microsecond portion on the time remaining, without
truncating unusual values.
