We currently upload the artifacts from running the install-mobile-dev target in Evergreen to S3 as

${project}/embedded-sdk/${build_variant}/${revision}/${version}.tgz
${project}/embedded-sdk/${build_variant}-latest.tgz

We should do something similar for the install-mobile-test target so that the mongoebench binary from SERVER-35537 can be run on an Android device. The following S3 paths were proposed by acm:

${project}/embedded-sdk-test/${build_variant}/${revision}/${version}.tgz
${project}/embedded-sdk-test/${build_variant}-latest.tgz
