initscripts: remove warnings on read-only-rootfs (again)
When the populate-volatile.sh initscript tests if a configured symlink
is already in place, it uses readlink with the '-f' (follow) option:
> [ "$(readlink -f $source)" = "$dest" ]
If the test fails, it proceeds to delete the exisiting folder/file, and
create the configured symlink.
However, the '-f' option to readlink makes it follow symlinks pointing
at symlinks. If the $dest argument is a symlink, the above test fails,
and warnings are printed due to changing a read-only rootfs.
This is the case for /tmp, and /etc/resolv.conf:
> /tmp -> /var/tmp -> /var/volatile/tmp
> /etc/resolv.conf -> /var/run/resolv.conf -> /run/resolv.conf
Fix the warnings by removing the '-f' option, so that the test matches
the configuration.
