Fix Bug#43309 Test main.innodb can't be run twice

Make the innodb mysql-test more flexible by inspecting how much a
variable of interest has changed since the start of the test. Do not
assume the variables have zero values at the start of the test.

# Small basic test with ignore
#
# Save the original values of some variables in order to be able to
# estimate how much they have changed during the tests. Previously this
# test assumed that e.g. rows_deleted is 0 here and after deleting 23
# rows it expected that rows_deleted will be 23. Now we do not make
# assumptions about the values of the variables at the beginning, e.g.
# rows_deleted should be 23 + "rows_deleted before the test". This allows
# the test to be run multiple times without restarting the mysqld server.
