Consolidate defaults for hostside network tests apps.

For now, only share a couple of statements (min_sdk_version and
platform_apis). More will be added later.

Also, remove the test_suites stanzas everywhere. These are not
relevant for test apps because the APKs will be pulled in by
the data: stanzas anyway.
