fix: Fix the libqrencode build under MacOS 10.15

[nickolay168]

In MacOS 10.15 I have stareted seeing the CI failures as follows:

cmake . -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/Users/runner/work/deps -DCMAKE_OSX_DEPLOYMENT_TARGET=10.15 -DCMAKE_OSX_DEPLOYMENT_TARGET=10.15 -DWITH_TOOLS=OFF -DBUILD_SHARED_LIBS=OFF
CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.


-- Configuring incomplete, errors occurred!

It is caused by this line in the libqrencode CmakeLists.txt. I have added -DCMAKE_POLICY_VERSION_MINIMUM=3.5 flag to redefine the minimal Cmake version.

Hi, @iphydf, In this PR I have updated the Bazel version to fix the build, but circleci uses script from the master branch and I cannot test my changes. Would it be possible to run test from my branch to see if Bazel upgrade fixes the issue?

I extracted that change to #201 . Let's see if that fixes the issue.

@nickolay168 If you remove the bazel change we can merge this as a workaround.
