Subject: [PATCH 2/3] MDEV-30837: Remove usage of AWK from Debian init and
 postinst scripts

AWK in used in Debian SysV-init and postinst scripts to determine
is there enough space starting MariaDB database or create new
database to target destination.

These AWK scripts can be rewrited to use pure SH or help
using Coreutils which is mandatory for usage of MariaDB currently.

Reasoning behind this is to get rid of one very less used dependency
