Avoid -Werror,-Wcast-function-type-mismatch

...as seen when building LOWA (i.e., --disable-dynloading) with a recent Clang
with
<https://github.com/llvm/llvm-project/commit/999d4f840777bf8de26d45947192aa0728edc0fb>
"Split -Wcast-function-type into a separate group (#86131)", where
-Wcast-function-type-mismatch generally warns about casts between incompatible
function types...

> cppuhelper/source/shlib.cxx:294:23: error: cast from 'void *(*)(void *, void *)' to 'ImplementationConstructorFn *' (aka 'css::uno::XInterface *(*)(css::uno::XComponentContext *, const css::uno::Sequence<css::uno::Any> &)') converts to incompatible function type [-Werror,-Wcast-function-type-mismatch]
>   294 |                     = reinterpret_cast<ImplementationConstructorFn *>(

...but not for the special case of casting from/to void(*)(void).

(Using the correct function type

> css::uno::XInterface * (*)(css::uno::XComponentContext *, css::uno::Sequence<css::uno::Any> const &)

throughout would be even better, but doesn't easily fit into this C code that is
included in low-level places that don't know those UNO types and is shared
between LOWA and Android etc.)
