Notes for libsavitar - reproducible builds result

Version annotated: 4.13.0-2
Identified issues:
Identifier: cmake_rpath_contains_build_path
Description When an executable is linked with a shared library from the same project,
RPATH will contain the build path. Even if this is stripped on installation,
the build-id will remain unchanged.
With CMake 3.14+, packages can set `-DCMAKE_BUILD_RPATH_USE_ORIGIN=ON` to
fix the issue. This is done automatically when using the currently
experimental debhelper compat level v14.
When working with older CMake versions, the `CMAKE_SKIP_RPATH` option can be
enabled instead, but it may be required to also set `LD_LIBRARY_PATH` while
running tests.
Comments: cmake rpath issue fixed by patching in
CMAKE_BUILD_RPATH_USE_ORIGIN=ON in CMakeLists.txt (as debian/rules
uses pybuild instead of cmake)
