archiver.bbclass: enhance do_ar_recipe task signature
Previously, do_ar_recipe ran again unnecessarily when adding or
removing classes like buildhistory.bbclass, because that changes the
BBINCLUDED variable which do_ar_recipe uses to find .bbappend files.
This is both extra work and also sometimes triggered "basehash
changed" errors (seen under oe-selftest, which adds machine.inc and
bblayers.inc) because BBINCLUDED is special and does not cause
the basehash to be recalculated.
The file *content* already was not considered in the task signature,
instead relying indirectly on PF (which includes the revision assigned
by a PR server) to ensure that a new versioned source archive gets
created each time there is a rebuild.
Therefore it makes sense to use the same mechanism and also ignore the
file *list*, i.e. exclude BBINCLUDED from the task signature.
