Fix issues with replacing unowned symlinks

There aretwo seperate issues in the same block of file conflict
checking code here:
1) If realpath errored, such as when a symlink was broken, we would call
   'continue' rather than simply exit this particular method of
   resolution. This was likely just a copy-paste mistake as the previous
   resolving steps all use loops where continue makes sense. Refactor
   the check so we only proceed if realpath is successful, and continue
   with the rest of the checks either way.
2) The real problem this code was trying to solve was canonicalizing
   path component (e.g., directory) symlinks. The final component, if
   not a directory, should not be handled at all in this loop. Add a
   !S_ISLNK() condition to the loop so we only call this for real files.

There are few other small cleanups to the debug messages that I made
while debugging this problem- we don't need to keep printing the file
name, and ensure every block that sets resolved_conflict to true prints
a debug message so we know how it was resolved.

This fixes the expected failures from symlink010.py and symlink011.py,
while still ensuring the fix for fileconflict007.py works.
