 Hadrian: work around Cabal's/GHC's different Arch/OS strings

 The path to the 'include' subdirectory of 'rts' includes a folder that
 whose name is generated by Cabal and mentiones the architecture and OS.
 For example:

     _build/stage1/lib/x86_64-osx-ghc-8.7.20181120/rts-1.0/include

 Hadrian needs to be aware that Cabal renders architectures and OSes in
 a slightly different way than GHC. There is already symmetric logic in
 Cabal (for working with GHC environment files, which follow GHC's naming
 conventions).

 Test Plan: ./hadrian/build.sh -c "binary-dist" # on mac
