haskell-generic-builder: allow passing flags to the test suite(s)

Browse source 
Every flag the generic builder receives via `testFlags` is passed via
`--test-option` [1] to `Setup.hs` which in turn passes them to the
underlying test suite binary. These wrapped options are added to
`checkFlagsArray` in `checkPhase`. This needs to be done in bash since
without structuredAttrs in nixpkgs so far, Nix arrays aren't properly
translated into bash arrays, so we'd have all sorts of quoting issues
when spaces are involved.

Re-using `checkFlags` and `checkFlagsArray` from standard stdenv
setup.sh also results in an additional feature: Using `overrideAttrs`
`checkFlags` and `checkFlagsArray` can additionally be overridden,
which allows passing extra flags to `Setup.hs` whithout being wrapped
with `--test-option`.

[1]: See also https://cabal.readthedocs.io/en/3.4/setup-commands.html?highlight=test-option#cmdoption-runhaskell-Setup.hs-test-test-option
     According to the cabal-install man page this also allows passing
     special variables which are substituted for other values
     depending on context.
