  [llvm][cmake] Make `install_symlink` workflow work with absolute install dirs

If `CMAKE_INSTALL_BINDIR` is a different absolute path per project, as
it is with NixOS when we install every package to its own prefix, the
old way fails when the absolute path gets prepended with `CMAKE_INSTALL_PREFIX`.

Using `extend_path` from the install-time script isn't really possible, so we just make the caller responsible for making the path absolute instead.

Also fix one stray `bin` -> `CMAKE_INSTALL_BINDIR`
