classes/buildhistory: avoid buildhistory triggering rebuilds (again)
Postfuncs are now incorporated into task signatures as of BitBake
rev
b84d010144de687667cf855ddcb41c9b863c236e, so we need to exclude
the one we're adding to do_fetch. The change to the SSTATEPOSTINSTFUNCS
variable value was also entering the signatures of do_populate_sysroot
and probably other tasks, so we need to use a slightly hacky trick to
avoid that as well.
Apart from the final do_rootfs / do_populate_sysroot, this now means
that adding and removing INHERIT += "buildhistory" will not cause tasks
to be re-run.
Also update the copyright date, properly this time.
