dev-python/requests: Support running tests without trustme

In preperation for trustme losing keywords due to Rust requirement, make
it possible to run the vast majority of requests' tests without it (only
one test requires the dependency).

+Subject: [PATCH] Skip the test requiring trustme when it is not available
+
+Modify the nosan_server fixture to cause test_https_warnings to be
+skipped when trustme is not installed on the system, rather than causing
+the whole test suite to fail unconditionally.  This makes it possible
+to run all the remaining tests on systems where trustme cannot be
+installed due to its dependencies.
