[Bug 2133760] [NEW] Curtin does not respect update_nvram option

Public bug reported:

When installing ubuntu via curtin the grub: update_nvram option is set
to false in my configuration. However upon install, the grub-multi-
install script is used which does not pass the --no-nvram argument to
grub-install. The offending code seems to be at
curtin/commands/install_grub.py at line 336. If the regular grub install
command is used, the --no-nvram argument is added based on the curtin
config, but this does not occur in any way for when GRUB_MULTI_INSTALL
is the grub_cmd in use.
