MDEV-30220: rsync SST completely ignores aria-log-dir-path

This commit adds support for the --aria-log-dir-path
option on the command line and for the aria-log-dir-path
option in the configuration file to the SST scripts, since
before this change these parameters were completely ignored
during SST - SST scripts assumed that aria logs files are
always located in the same directory as logs for innodb.

Tests for this change will be added as a separate commit,
along with tests for MDEV-30157 and MDEV-28669.
