YCMBootstrap-not-use-system and YCMBootstrap-disable-find test fail on conda-forge packaging CI

[traversaro]

Not a big issue (I can disable the failing tests, but the YCMBootstrap-not-use-system and YCMBootstrap-disable-find tests are failing on Windows/macOS/Linux conda-forge packaging CI. For example, on Linux the test failures are:
