The functions bb_perror_nomsg() and bb_perror_nomsg_and_die() are
used to print error messages where no specific information is
available.  For example:
   $ busybox mktemp -p /
   mktemp: (null): Permission denied
mktemp(3) doesn't tell us the name of the file it tried to create.
However, printing '(null)' is a regression introduced by commit
6937487be (libbb: reduce the overhead of single parameter bb_error_msg()
calls).  Restore the previous behaviour by reverting the changes to
the two functions mentioned:
   $ busybox mktemp -p /
   mktemp: Permission denied
function                                             old     new   delta
bb_perror_nomsg_and_die                                7      14      +7
bb_perror_nomsg                                        7      14      +7
