Update usages of min_sdk_version that relies on (kind+level)

The type of min_sdk_version is being migrated from
android.SdkSpec(kind+level) to android.ApiLevel(level). This affects
`ShouldSupportSdkVersion` for java modules. This function skips the
check for modules compiling against `core`, and that requires access to
SdkVersion and not MinSdkVersion after the migration.

Skip the check explicitly using SdkVersion.
