Merge bitcoin/bitcoin#27312: depends: qrencode 4.1.1

eb1c3ad depends: qrencode 4.1.1 (fanquake)

Pull request description:

  Upgrade to the latest qrencode, and disable some warnings that cause compile failures with newer compilers (clang-15+).

  I haven't tested this (from a GUI perspective) at all. This is just "good enough" to keep things compiling, and uses some similar work-arounds as we have with other older packages, i.e bdb.

  Note that upstream, libqrencode is effectively unmaintained. No code changes for > 2 years. No responses to issues/PRs. Seems like the author has mostly dropped off of GitHub as well.

  This fixes part of #27299.
