NodeConfig ignores /var which also break other folders when symlinked

[tnozicka]

On CoreOS like fs, all data is efectivelly stored in /var/ and other folders point to it:

lrwxrwxrwx.   2 root root    7 Nov 20  2023 bin -> usr/bin
drwxr-xr-x.   8 root root 1024 Jul 19 09:14 boot
drwxr-xr-x.  17 root root 3720 Jul 19 14:23 dev
drwxr-xr-x.  96 root root 8192 Jul 19 14:23 etc
lrwxrwxrwx.   2 root root    8 Nov 20  2023 home -> var/home
lrwxrwxrwx.   2 root root    7 Nov 20  2023 lib -> usr/lib
lrwxrwxrwx.   2 root root    9 Nov 20  2023 lib64 -> usr/lib64
lrwxrwxrwx.   2 root root    9 Nov 20  2023 media -> run/media
lrwxrwxrwx.   2 root root    7 Nov 20  2023 mnt -> var/mnt
lrwxrwxrwx.   2 root root    7 Nov 20  2023 opt -> var/opt
lrwxrwxrwx.   2 root root   14 Nov 20  2023 ostree -> sysroot/ostree
dr-xr-xr-x. 237 root root    0 Jul 19 14:22 proc
lrwxrwxrwx.   2 root root   12 Nov 20  2023 root -> var/roothome
drwxr-xr-x.  56 root root 1480 Jul 19 14:23 run
lrwxrwxrwx.   2 root root    8 Nov 20  2023 sbin -> usr/sbin
lrwxrwxrwx.   2 root root    7 Nov 20  2023 srv -> var/srv
dr-xr-xr-x.  13 root root    0 Jul 19 14:22 sys
drwxr-xr-x.   4 root root   66 Nov 20  2023 sysroot
drwxrwxrwt.  11 root root  220 Jul 19 17:41 tmp
drwxr-xr-x.  12 root root  155 Jan  1  1970 usr
drwxr-xr-x.  24 root root 4096 Jul 19 09:13 var

but NodeConfig doesn't mount say /var at all

scylla-operator/pkg/controller/nodeconfig/resource.go

Line 251 in d0ccf55

for d in $( find /host -mindepth 1 -maxdepth 1 -type d -not -path /host/var -not -path /host/run -not -path /host/tmp -printf '%f\n' ); do

So while we can now resolve symlinks, the path actually doesn't exist and can't be resolved, neither used.
