macos: use DYLD_FALLBACK_LIBRARY_PATH instead of DYLD_LIBRARY_PATH
`DYLD_LIBRARY_PATH` can frequently break builtin macOS software when pointed at Spack libraries. This is because it takes *higher* precedence than the default library search paths, which are used by system software. `DYLD_FALLBACK_LIBRARY_PATH`, on the other hand, takes lower precedence. At first glance, this might seem bad, because the software installed by Spack in an environment needs to find *its* libraries, and it should not use the defaults. However, Spack's isntallations are always `RPATH`'d, so they do not have this problem. `DYLD_FALLBACK_LIBRARY_PATH` is thus useful for things built in an environment that need to use Spack's libraries, that don't set *their* RPATHs correctly for whatever reason. We now prefer it to `DYLD_LIBRARY_PATH` in modules and in environments because it helps a little bit, and it is much less intrusive.
