sort svgz file list

(required because filesystems return listings in undeterministic order)
to generate Resources.qrc and thereby Resources.cpp and the lyx binary
in a reproducible way

Setting LC_ALL=C because sort order might vary with locales.

See https://reproducible-builds.org/ for why this matters.

Fixes #10711.
