Add bats asserts (#463)

* Added `bats-assert` for more detailed error, very useful locally and on Travis
* Moved `bats` to git submodule

Example:

```
not ok 52 checking opendkim: generator creates keys, tables and TrustedHosts
# (from function `assert_output' in file test/test_helper/bats-assert/src/assert.bash, line 239,
#  in test file test/tests.bats, line 368)
#   `assert_output 2' failed
# 
# -- output differs --
# expected : 2
# actual   : 4
# --
# 
```
