test(android): Stop memory limiter tests waiting on flush timeouts (#6211)

MemoryLimiterIntegrationTest and ApplicationExitInfoCrossIntegrationTest kept
the default 15s flush and session flush timeouts. Nothing in these tests
releases those latches, so every integration registration and every captured
event blocked for the full timeout. The two classes took about 8 minutes
combined and now take under 2 seconds.

Also drop the manual cache dir cleanup in these two tests and in
AnrV2IntegrationTest. The TemporaryFolder rule already deletes it after each
test.
