pacman/packages.c : print an error for files that can't be stated.

The -Ql operation is supposed to print all files but directories.
stat was used for detecting directories. However, when stat failed,
(because the file doesn't exist or is not readable), the files
were still displayed just like the others.

Now, these files are printed on stderr, with the corresponding error message.
