haskell.compiler: fix binary GHCs with store paths containing "xxx"

At some point in hadrian's installation Makefile used for e.g. alpine
bindists 'xxx' is used as a placeholder for three spaces and later
substituted back. This breaks if the store path itself contains 'xxx'.
We adapt an upstream patch which will be part of 9.4 (and presumably
9.0.3 and 9.2.3) as a workaround for this issue for 8.10.2 and 8.10.7
which are the binary GHCs in nixpkgs affected.
