Bug#4524: controllib.pl doesn't show file name in error msg

[Karl Sackett]

Package: dpkg-dev
Version: 1.4.0

While tracking down a different bug, I found this typo on line 58 of
/usr/lib/dpkg/controllib.pl:

        &error("unable to open substvars file $varlistvile: $!");
                                              ^^^^^^^^^^^^

I changed this to '$varlistfile' and now controllib.pl now tells me which
substvars it can't open instead of printing a blank space.
