Fix processing of first path in SOLARINC

...which does not have a space before the -I, so copying starting at pos+3
dropped the leading character from the path.  This was apparently never a
problem in practice, as the first path in SOLARINC happens to always be
SRCDIR/include, which should not be needed anyway when building external
projects with this GCC wrapper on Windows.

(So this commit is a change in behavior, making SRCDIR/include available to
those external project builds on Windows, but the follow-up commit
<https://gerrit.libreoffice.org/c/core/+/128615> "Decouple SRCDIR/include from
SOLARINC" will change the behavior back again.)
