Replace all references to /usr/sbin/mysqld (and bin and libexec) with
mariadbd, so that the binary server will always be 'mariadbd'.
Also update all places that reference the server binary in other ways,
such as AppArmor profiles and scripts that previously expected to find
a 'mysqld' in process lists.
Fix of Bug#25088048 caused paths to be relative, not absolute, this
proved to be problematic.
Fix is to still ignore current working directory, however switch to
using full path of basedir, which is set to parent directory of bin/
directory where mysqld_safe is located.
References to legacy tool mysql_print_defaults are removed, only
my_print_defaults is used these days.
This will also fix:
