Update old Perls from jessie to stretch (and test them all in Actions)

Additionally, add buster to all of them.

Finally, move all EOL versions into a completely separate `eol/` directory so that the repository is a little easier manage (and so we can limit testing of all old EOL versions to only when something inside the `eol/` directory changes).

+-	#
+-	# To make a long story short, making sure that the *.a and *.sa pairs of
+-	#   /usr/lib/lib{m,db,gdbm}.{a,sa}
+-	# were perfectly in sync took care of it.
