linux-boot: Don't ignore options when mounting root file system.
Fixes <https://bugs.gnu.org/37977>. * gnu/build/linux-boot.scm (mount-root-file-system): Add the 'options' keyword argument and use it when mounting the root file system. (boot-system): Pass the root file system options to 'mount-root-file-system'. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
