Subject: [PATCH] [Tests] switch to use Cabal to install ShellCheck

1. This can help speed up the apt process since we decrease the
complexity of apt sources and package dependencies resolving by dropping
an additional ppa source.

2. Stack doesn't update ShellCheck to v0.4.5 after it has been released
more than one month, Cabal can provide ShellCheck v0.4.5
