Always pass `ghc-options` (#8717)

* Always pass `ghc-options`

The [documentation for `ghc-shared-options`][1] states that they are
combined with `ghc-options`:

> Additional options for GHC when the package is built as shared
> library. The options specified via this field are combined with the
> ones specified via `ghc-options`, and are passed to GHC during both
> the compile and link phases.

However, _only_ `ghc-shared-options` and not `ghc-options` are passed in
many cases.

This is an issue because it requires setting `ghc-shared-options` even
if the shared (dynamic) parts of the build don't actually need different
options; this has the unpleasant side-effect of causing modules to be
compiled twice, effectively doubling compile time! See here, where any
non-empty `ghc-shared-options` causes Cabal to not set `-dynamic-too`:

This issue was discovered while integrating the `mold` linker with a
Haskell project.
