Build apps for CTS tests with sdk 31

We need to run those CTS tests on older devices for mainline. It turns
out that min_sdk_version is not enough.

Also, the reporter app does not need to run on MTS, so there's no need
to build it for sdk 31.

Tested: built the test apps and installed them on older devices (it
failed before).

Tested: atest CtsPerfettoTestCases
