Chez Scheme: avoid hard-coded paths for utilities in build scripts

These changes facilitate building Chez Scheme in environments where
utility commands are not available at their usual absolute paths,
such as Nix and GNU Guix.

Specific changes:
  - `cc` -> `$(CC)`
  - `/bin/rm` -> `rm`
  - `/bin/ln` -> `ln`
  - `/bin/cp` -> `cp`
  - `/bin/echo` -> `echo`
  - in `makefiles/installsh`, add a case to find `true`
    at an unusual path or as a shell builtin
