run_self_tests() now takes the same effective AppConfig any other command
gets and stashes it into a new g_test_app_config global (tests/support/
fixtures.h) before Catch2 runs anything. test_rootless_run.cpp's own
run_in_fixture() reads a copy of it instead of a hardcoded default
AppConfig{}, so -c actually reaches that test's container creation.
Verified: a config with every unshare-*/with-* key set to false, used via
-c <file> -t -- "[integration][net]~[root]", flips all 3 of that file's
container-creating tests to failing -- including the nohup-straggler
regression test, since with neither a pid namespace nor a cgroup nothing
reaps the backgrounded process -- while [unit] and non-networking
[integration] tests are completely unaffected, as expected.
