bootstat: record reboot reason history in persist.sys.boot.reason.history
Retain the last four reboot reasons from latest to oldest, adding a detail of UTC epoch time for each. Beef up boot_reason_test.sh to deal with multi-line content. Test: boot_reason_test.sh Bug: 110925971 Change-Id: Ie2600434b95a885693f005a363ee38d9eba18ee7
