[OE-core] [oe-core][rocko][sumo][master][PATCH 1/2] bitbake.conf: add PERSISTENT_LOG_DIR variable

[Ankur Tyagi]

This variable is only respected when VOLATILE_LOG_DIR is "no".

The default value is "" which results in the /var/log being log directory.

The user could override this value to a path e.g "/home/root/log" which
results /var/log being a link pointing to /home/root/log directory on
persistent storage.
