Vlad Lesin edda2fd149 MDEV-20703: mariabackup creates binlog files in server binlog directory on --prepare --export step ...

When "--export" mariabackup option is used, mariabackup starts the server in
bootstrap mode to generate *.cfg files for the certain innodb tables.
The started instance of the server reads options from the file, pointed
out in "--defaults-file" mariabackup option.

If the server uses the same config file as mariabackup, and binlog is
switched on in that config file, then "mariabackup --prepare --export"
will create binary log files in the server's binary log directory, what
can cause issues.

The fix is to add "--skip-log-bin" in mysld options when the server is
started to generate *.cfg files.
