virt-result.m4: Align string more generously
virt-result.m4: Align string more generously

The times, when we had small CRTs are long gone. Now, in the era
of wide screens we can be more generous when it comes to aligning
the output of configure. The longest string before the colon is
'wireshark_dissector' which counts 19 characters.  Therefore,
align the strings at 20.

At the same time, drop the useless result alignment. It behaves
oddly - it puts a space at the end of each "no" because of the
%-3s format we use.
