1. Fixed leakage of a file descriptor for every non-fatal failure in

rm_overwrite() (for rm -P).

2. Print the file name in the error message for (fatal) malloc() failures
   in rm_overwrite().  I first thought that malloc() failures should be
   non-fatal since they don't prevent proceeding the the next file, but
   making them non-fatal would normally give too much output for rm -Pr
   on a large tree in the unlikely event that even one occurs, since the
   malloc()ed amounts are usually the same.  Just print the file name since
   the malloc()ed amounts are not always the same and it doesn't hurt to
   know where rm was when it quit.
