libfs_avb: support rollback protection for Live GSI This commit extracts the security patch level (SPL), e.g., com.android.build.system.security_patch = 2019-04-05 from AVB property descriptors when attempting to mount a standalone image (e.g., live GSI). Then compares the SPL between the old system.img and the new live system.img for rollback protection. Bug: 122705329 Test: boot an old Live GSI, checks rollback is detected Change-Id: I7aae58c0b2062a3ff57ed932ad58e7b604453fed
