systemd-hwdb update is an expensive operation by itself, and when running with sanitizers and in a VM without acceleration this cost is exacerbated even further, making the test run for a very long time. For example, in the daily CentOS CI ppc64le job with ASan+UBSan one systemd-hwdb update takes more than 7 minutes; in the regular Arch job with KVM it takes over 2 minutes. Since the hwdb update is also tested in other places (like TEST-01-BASIC and the test-hwdb meson test), let's skip it if we detect we run with sanitizers and with plain QEMU.
