selftests/bpf: libarena: Add parallel bitmap selftest

Browse source

Add a selftest for testing the atomic bitmap set/clear/
test_and_set/test_and_clear operations. The selftest
checks atomicity by spawning two threads, each of which
either only works on even bits or with odd bits. The
test checks that threads do not affect each other's
bits.
