Frantisek Sumsal 1e42972958 test: make TEST-64 a bit more ASan friendly
Reduce the number of iterations in some of the test cases, since they
generate a huge amount of uevents and basically DoS udev (which can't
keep up while being slowed down by ASan). To avoid this, let's reduce
the number of iterations and bump the timeout when running under ASan,
since we're not interested in performance in such cases.
