devel/hs-ShellCheck: Link Haskell dependencies statically

ShellCheck is an essential tool that should not require having the
entire Haskell toolchain installed which most users do not need.

The installed size (including all run dependencies) goes down from
~2 GiB to ~35 MiB. This brings the hs-ShellCheck package more in
line with what is provided by various Linux distributions and
OpenBSD.
