Do not break symlinks in dom0 home backup

[marmarek]

Currently all relative symlinks have target "current" directory replaced by "dom0-home". This is caused by this line:

tar
(...)
'--xform', 's:^[% filename["subdir"](^/]:%s\\0:'),

which canonicalize file names. The problem is that option affect also link targets, not only stored file names.

Not ideal but greatly limit damage (now breaks only relative links pointing at directory named same as dom0 user).
