Set targetSdkVersion to 10000 for MTS tests targeting current

MTS tests built on unstable branches (e.g. git_master) should be testable on
old system images (e.g. S). However, they run into an error during installation
on older images:
`Requires development platform $<current_codename>, but this is a
release platform`

This CL fixes this issue by updating the target_sdk_version of MTS test apps
targeting current to the magical sdk_version 10000
