cmd/cgo/internal/testsanitizers: failures with `setarch: failed to set personality to x86_64: Operation not permitted`

Proposal Details

I'm seeing the following error when running gotip tool dist test in a Ubuntu 22.04 container image:

--- FAIL: TestShared (0.00s)
    --- FAIL: TestShared/tsan_shared (8.58s)
        cshared_test.go:105: /usr/bin/setarch x86_64 -R /tmp/TestShared2916998830/tsan_shared exited with exit status 1
            setarch: failed to set personality to x86_64: Operation not permitted
--- FAIL: TestTSAN (51.46s)
    --- FAIL: TestTSAN/tsan (1.95s)
        tsan_test.go:88: /usr/bin/setarch x86_64 -R /tmp/TestTSAN2318749046/tsan exited with exit status 1
            setarch: failed to set personality to x86_64: Operation not permitted

The setarch normally needs the --privileged flag to be passed to docker run, but I would rather try to avoid that. In fact, setarch was introduced in CL 623956 to fix the following test issue: #59418, which it did, but also introduced the issue reported in here.
