ad35d522db Fixes 5370 infinite/maxLoopCount loop for relative symlinks
use path.IsAbs() instead of checking if first char is '/'

b51c366bfc Defend against infinite loop when following symlinks
ideally it should never reach it, but there was already multiple issues with infinite loop
at following symlinks. this fixes hanging unit tests

8b77a5b7ae Adding test case for symlink causes infinit loop, reproduces: dotcloud#5370
normally symlinks are created as either
ln -s /path/existing /path/new-name
or
cd /path && ln -s ./existing new-name

but one can create it this way
cd /path && ln -s existing new-name

this drives FollowSymlinkInScope into infinite loop
