package/qt5/qt5base: remove leftover patch

CVE-2021-38593 fixes originally missed a usecase that was covered by the
to-be-removed patch. However, this patch was incorrect and added some
issues on its own, which was then fixed by now-removed
0012-Refix-for-avoiding-huge-number-of-tiny-dashes.patch.

Unfortunately for us, the to-be-removed patch (fixed by
0012-Refix-for-avoiding-huge-number-of-tiny-dashes.patch) can actually
be applied (with fuzz; by `patch` only) on top of the now-removed patch.
When the move to KDE Qt fork was made, some patches were removed as they
were already part of the new git fork. However, the to-be-removed patch
was not. This means the
0012-Refix-for-avoiding-huge-number-of-tiny-dashes.patch was actually
undone when Buildroot patched qt5base.

Let's remove this patch to fix this oversight.

As a reference:
e7ea2ed27c Improve fix for avoiding huge number of tiny dashes
fixed by
65b3aa6a1c Refix for avoiding huge number of tiny dashes
in the git repo.
