MDEV-39318 MTR: fix test failures when running with --ssl

make sure P_S.{global|session}_status and I_S.feedback plugin table
have a column of the same width as I_S.global_status.

Otherwise long status strings (e.g. Ssl_cipher_list) won't fit
and trigger a data truncation warning (an error in the strict mode)
