branches/zip: windows plugin - fix references to array variables.

This problem surfaced when running new test innodb_bug40360.test. Both
tx_isolation_names and binlog_format_names are name arrays, and
should be defined as wdl_tx_isolation_names and wdl_binlog_format_names,
not *wdl_tx_isolation_names and *wdl_binlog_format_names.

Another array variable is all_charsets, which is already correctly
defined.
