Add default LMK properties to GSI

These LMK properties are product properties. The configuration will
be absent when GSI is installed as GSI doesn't mount the product
partition. Without these settings, some CTS test cases could
fail due to an aggressive LMK.

The patch puts these properties in GSI as default values.

Bug: 134460917
Test: `run cts -m CtsFileSystemTestCases`, all pass
