CI timeouts on 'gcov' job: test-bufferiszero, test-crypto-tlscredsx509
The 'gcov' job is a bit flaky; some jobs time out sometimes:
https://gitlab.com/qemu-project/qemu/-/jobs/6367913150
119/120 qemu:unit / test-bufferiszero TIMEOUT 30.14s killed by signal 15 SIGTERM
120/120 qemu:unit / test-crypto-tlscredsx509 TIMEOUT 45.20s killed by signal 15 SIGTERM
https://gitlab.com/qemu-project/qemu/-/jobs/6313212690
120/120 qemu:unit / test-bufferiszero TIMEOUT 30.09s killed by signal 15 SIGTERM
https://gitlab.com/qemu-project/qemu/-/jobs/6280179242
120/120 qemu:unit / test-bufferiszero TIMEOUT 30.03s killed by signal 15 SIGTERM
https://gitlab.com/qemu-project/qemu/-/jobs/6269183359
119/120 qemu:unit / test-bufferiszero TIMEOUT 30.07s killed by signal 15 SIGTERM
https://gitlab.com/qemu-project/qemu/-/jobs/6246367144
120/120 qemu:unit / test-bufferiszero TIMEOUT 30.02s killed by signal 15 SIGTERM
We should start by doubling the timeout on these two tests, I guess.
