[runtime tests] Exclude failing python and java tests

test_httplib was un-excluded in cl/325137657. Exclude it again.
test_httplib fails consistently when running in a kokoro job. Could not repro
with Docker.

There are some java tests that pass locally on Docker but fail when running
within a kokoro job.

Also make shard count a multiple of 8 to minimize idle cores and minimize test
time.
