Testing odbc+wx on OTP 20.3 on a slim jessie (#271)

* wx-20.3: seeing about kerl/kerl/issues/270

* wx-20.3: less failible test + less deps

* wx-20.3: move linux tests out of TravisCI into CircleCI

* wx-20.3: always use git backend (erlang.org is still down)

* wx-20.3: work around fact that erlang.org is down in .travis.yml

* wx-20.3: fix some things

* wx-20.3: looks like skipping happens too late

* wx-20.3: that did not fix it (cc @mrallen1)

* wx-20.3: shellcheck stable segfaults?

* wx-20.3: should fix shellcheck segfault

* SC1117: Backslash is literal in "\!". Prefer explicit escaping: "\\!".

Not sure about the csh one. @mcrallen1 you have a clue?

* wx-20.3: SC2207: Prefer mapfile or read -a to split command output (or quote to avoid splitting).

* wx-20.3: SC2154: words is referenced but not assigned.

* wx-20.3: replace some double quotes with simple ones

* wx-20.3: ps not found on debian9!?
