simpleperf: fix tests for dwarf callgraph unwinding.
32-bit simpleperf can't unwind a 64-bit `sleep` process in aarch64
environment. It makes following error in tests:
simpleperf is built in arch arm, and can't do stack unwinding for arch arm64
So make the workload be able to start a process
running callback function. By profiling that process, we can
guarantee that 32-bit simpleperf is profiling a 32-bit process.
Also fix a flaky test IOEventLoop.signal.
Build 32-bit simpleperf_unit_test on 64-bit devices.
Bug: http://b/33167911
Test: run simpleperf_unit_test.
