[BUG] (deleted) flag doesn't take in consideration symlink

[henri9813]

Describe the bug
(deleted) flag has false-postifi when related to a symlink

To Reproduce

1. Have /sbin symlink to /usr/sbin
2. Run a process /usr/sbin/NetworkManager
3. run lsof |grep "(deleted)"

Network manager is considered "deleted" whereas the file is present.

Expected behavior
The file should not be considered as deleted
