#1946 scintilla does not build reproducibly

[Bernhard M. Wiedemann]

When working on reproducible builds for openSUSE I found that
libscintilla.so.3.0.0 build results differ between builds because filesystem order is random and ordering matters for the g++ linker.

Please apply the attached patch

See https://reproducible-builds.org/ for why reproducible builds are a good thing.

The patch was based on an old version of Scintilla and didn't apply so a similar change was made as [57945d].
