linux-boot: Ensure /etc exists on the root file system.
Fixes a regression introduced in c8289690365887ca1dd122645e479a89cf7cd969 whereby /etc would no longer be created as a result of calling 'mark-as-not-killable'. This would affect ISO images because 'make-iso9660-image' does not create /etc by default. In particular, the ISO installation image as created by the "iso-image-installer" test would fail to boot while creating the /root/etc/mtab symlink: <https://hydra.gnu.org/build/2352514/nixlog/9/raw>. * gnu/build/linux-boot.scm (mount-root-file-system): Make sure /root/etc exists.
