MDEV-22010: use executables MariaDB named in scripts

As a part of this MDEV following changes were made: 1) Mariadb named executables used instead of mysql named executables in scripts 2) renamed mysql-test-run and mysql-stress-test to mariadb-test-run and mariadb-stress-test and created a symlink.

this doesn't make much sense. there was never a mariadb_safe tool, was it? if there was not, then you don't need to search for it, just write m/\/mariadbd-safe$/ although I'd rather written m[/mariadbd-safe$] - if / is not used as a delimiter, there's no need to escape it in a regex.

here it should, probably, say "to start mariadbd" ?
