Fix again snapshots saving /var

See this blog post a couple of days ago:

• Fix snapshots not saving /var — January 28, 2025

Caramel reported a problem with that fix, so had another go at it, see github:

I have also included a test if /var is a symlink; in that case, exclude all of /var. Earlier versions of EasyOS had /var as a symlink into /tmp/var, with /tmp a mounted tmpfs. Then subfolders in /tmp/var where symlinks to actual folders inside /root

A bit convoluted, but if I ever decide to go that way again, might as well have the code that detects that situation, /var being a symlink.

Note, the rationale for /var being a symlink was before changed Easy to run in RAM, when there were direct writes to the working-partition. This arrangement reduced writes to the storage media.
