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.
