Fix make binary-dist when using USE_BINARYBUILDER_LLVM=0 (#55731)

`make binary-dist` expects lld to be in usr/tools but it ends up in
usr/bin so I copied it into usr/tools. Should fix the scheduled source
tests which currently fail at linking.

I think this is also broken with `USE_BINARYBUILDER_LLVM=0` and
`BUILD_LLD=0`, maybe
ceaeb7b
is the fix?
