1. llvmPackages_{7-12}.compiler-rt: install resource files to DATADIR …

   This is in an effort to fix the following build failure shown by
   chromium:
   
       clang++: error: no such file or directory: '/nix/store/fhd89wrmkx6nflzjk0d6waz70bk3zc4i-clang-wrapper-12.0.0/resource-root/share/cfi_blacklist.txt'
   
   As it turns out a change introduced via the gnu-install-dirs.patch
   caused `add_compiler_rt_resource_file` to install resource files to
   $dev/include (FULL_INCLUDEDIR) instead of $out/share (FULL_DATADIR)
   which in turn meant that the clang wrappers we had didn't link those
   files to its resource root at all.
   
   Alternative fix to this would have been to link
   compiler-rt.dev/include/*.txt to the wrappers resource-root/share as
   well, but since this was handled inconsistently across the patch anyways
   (the dfsan list is installed correctly), opt to handle this
   consistently within the patch.
   
   llvmPackages_{5,6} install the resource files to a completely different
   location and need separate investigation.

2. llvmPackages_{7,8,9}: link ${compiler-rt.out}/share to resource root …

   This is done for 10-12, but not for the earlier llvm package sets.
