Subject: Download mplint release instead of recompiling every time

Saves 1min10s by not compiling and another 15s by moving it together with linters.

Squashed with:
* Make sure mplint internal error or failure to run is detected
* Make mplint breaking cause job to fail
* Move linters out of lightweight.. goes faster, 3m46s -> 1m45s
* Make script fail if any command returns nonzero or if any variable is
unset.
* Donwload mplint instead of building it
