Make tests pass after 2024

Tested on i586 and x86_64

Background:
As part of my work on reproducible builds for openSUSE, I check that software still gives identical build results in the future.
The usual offset is +15 years, because that is how long I expect some software will be used in some places.
This showed up 1 failing test in our rnp package build.
See https://reproducible-builds.org/ for why this matters.

This PR was done while working on reproducible builds for openSUSE.

20 tests have failed...

Interesting. These tests passed for me on openSUSE Tumbleweed.

[ RUN      ] rnp_tests.test_rnpcfg_get_expiration
/tmp/cirrus-ci-build/src/tests/utils-rnpcfg.cpp:130: Failure
Expected equality of these values:
  (get_expiration("3100-01-01", &raw_expiry))
    Which is: -3
  (0)
    Which is: 0

Maybe the test is good, but some of the implementation is bad?

Is it possible that you checked with the version 0.15.1? This commit probably changed the behaviour: 2ae6479

Expiration time, which is calculated there, cannot exceed 32bit unsigned (as it is stored as 32 bit uint in OpenPGP packets).
So maximum value should be not more than ~125 years from now.

LGTM, thanks @bmwiedemann !
