hadrian: fix bindist executable wrapper logic for cross targets

This commit fixes an oversight of hadrian wrapper generation logic:
when doing cross compilation, `wrapper` is called on executable names
with cross prefix, therefore we must use `isSuffixOf` when matching to
take the cross prefix into account. Also add missing cross prefix to
ghci wrapper content and fix hsc2hs wrapper logic.

(cherry picked from commit b57c2174cf8b4804d400c7db774565b2be4ff493)
