Fix handling of broken symlinks in filelib
This fixes a bug introduced in f11aabdc9fec593c31e6c4f3fa25c1707e9c35df where filelib:eval_read_file_info/2 was made to use file:read_link_info/1 to never follow symlinks. This fixed wildcard/1 but broke every other function using eval_read_file_info/2. Reported-by: Louis-Philippe Gauthier Reported-by: Danil Zagoskin
