BMC state manager support for LastRebootTime

Use the uptime value to calculate the time of the last
BMC reboot when the LastRebootTime property is read.

Calculates it on the fly instead of once at startup so that
if someone changes the BMC time the value will still be
accurate.

Resolves openbmc/openbmc#3159

Tested: Verify the property returns the right value.
