Add skip reason next to test name in zuul output

Currently our test names are long and we pipe pytest output to a file,
so the skip reason gets truncated; setting this env var .zuul and
passing to tox.ini will allow us to see the reason why pytest is
skipping next to the test name.

Drive-by: remove passenv from s3api tests in tox.ini so they are
inherited from testenv
