initscripts: SlugOS - add bootclean.sh to clean out /tmp, /var/lock, /var/run

(required when turned-up to disk).  Create SlugOS-specific volatiles config
because SlugOS needs /etc/resolv.conf to be static and not volatile.

+# This configuration file lists filesystem objects that should get verified

+# Understanding links:
+# When populate-volatile is to verify/create a directory or file, it will first
+# check it's existence. If a link is found to exist in the place of the target,
+# the path of the target is replaced with the target the link points to.
+# Thus, if a link is in the place to be verified, the object will be created
+# in the place the link points to instead.
+# This explains the order of "link before object" as in the example above, where
+# a link will be created at /var/test pointing to /tmp/testfile and due to this
+# link the file defined as /var/test will actually be created as /tmp/testfile.
