Bug #59489 Enable setting of env. variables for mysqld from mtr

Browse Source 
Added --mysqld-env option, propagate via safe_process
Simplified: should be safe to set in parent safe_process after it's started
Addendum: catch cases of --mysqld-env w/o value, assume env.var 
    name never begins with "--"
