Fix TAU_METRICS with multiple GPU backends

tau_exec was replacing `TIME with `TAUGPU_TIME` for every requested GPU
backend. So, for example, with ``-rocm -opencl`, we would get:
    `TIME` -> `TAUGPU_TIME` -> `TAUGPU_TAUGPU_TIME`
Fix by checking whether `TAUGPU_TIME` is already a metric before trying to
replace `TIME`.
