perf test: Remove atomics from test_loop to avoid test failures
The current use of atomics can lead to test failures, as tests (such as
tests/shell/record.sh) search for samples with "test_loop" as the
top-most stack frame, but find frames related to the atomic operation
(e.g. __aarch64_ldadd4_relax).
This change simply removes the "count" variable, as it is not necessary.

The count variable is incremented by multiple threads, doing so
without an atomic operation causes thread sanitizer warnings. Switch
to using relaxed atomics.

It also takes an optional argument to specify runtime in seconds
(default: 1).
