Subject: [PATCH] fix(dracut.sh): use printf instead of echo in mark_hostonly

POSIX requires to interpreted escape sequences. The filenames passed to
`mark_hostonly` might contain backslashes and therefore might be
interpreted (dash 0.5.13.1 will do that).

So use `printf` instead to avoid escaping the filenames.
