[patch] remove strver's leftover from error message in Solution.pm

[Anton Voloshin]

Hello,

in src/tools/msvc/Solution.pm (in the current master) there is a 
leftover from the past:
>                 confess "Bad format of version: $self->{strver}\n";
strver has been gone since 8f4fb4c6 in 2019, so I suggest an obvious 
one-line fix in the patch attached:

diff --git a/src/tools/msvc/Solution.pm b/src/tools/msvc/Solution.pm

-                               confess "Bad format of version:

                        }
                        $majorver = sprintf("%d", $1);
                        $minorver = sprintf("%d", $2 ? $2 : 0);

I think this should be backported to REL_13_STABLE, but not to 
REL_12_STABLE and earlier, where strver was still present.
