fa76b2f ci: Avoid boost test warnings (MarcoFalke)

Pull request description:

  This removes boost test warnings from the CI log.

  For example https://cirrus-ci.com/task/6029158399606784?logs=ci#L4060:

  ```
  Boost.Test WARNING: token "/tmp/cirrus-build/ci/scratch/build/bitcoin-x86_64-pc-linux-gnu/src/test/test_bitcoin-addrman_tests.o" does not correspond to the Boost.Test argument
                      and should be placed after all Boost.Test arguments and the -- separator.
                      For example: test_bitcoin --random -- /tmp/cirrus-build/ci/scratch/build/bitcoin-x86_64-pc-linux-gnu/src/test/test_bitcoin-addrman_tests.o
  Boost.Test WARNING: token "/tmp/cirrus-build/ci/scratch/build/bitcoin-x86_64-pc-linux-gnu/src/test/test_bitcoin-allocator_tests.o" does not correspond to the Boost.Test argument
                      and should be placed after all Boost.Test arguments and the -- separator.
                      For example: test_bitcoin --random -- /tmp/cirrus-build/ci/scratch/build/bitcoin-x86_64-pc-linux-gnu/src/test/test_bitcoin-allocator_tests.o
  Boost.Test WARNING: token "/tmp/cirrus-build/ci/scratch/build/bitcoin-x86_64-pc-linux-gnu/src/test/test_bitcoin-amount_tests.o" does not correspond to the Boost.Test argument
                      and should be placed after all Boost.Test arguments and the -- separator.
