Merge "Check UseRBE is set before replacing any template with the RE version." am: 3e0b9c031c

Original change: https://android-review.googlesource.com/c/platform/build/soong/+/1419252

Test:
1. Applied https://googleplex-android-review.git.corp.google.com/c/platform/build/soong/+/15723183, confirmed that the build fails on rvc-dev (by running `USE_RBE=false m `)
2. Subsequently applied this patch and tested to confirm that the failure is fixed (by running `USE_RBE=false m out/soong/.intermediates/vendor/qcom/sm7250/proprietary/commonsys/qcrilOemHook/qcrilmsgtunnel/android_common/combined/qcrilmsgtunnel.jar` and `USE_RBE=true m out/soong/.intermediates/vendor/qcom/sm7250/proprietary/commonsys/qcrilOemHook/qcrilmsgtunnel/android_common/combined/qcrilmsgtunnel.jar`).
