Subject: [PATCH] MDEV-35850 make HOSTNAME a cmake configure variable

As seen with openwrt and some other distros, the
determination of hostname can sometime need alternate
commmands.

This provides a cmake option HOSTNAME for non-windows machines
for the mariadb-install-db and mariadbd-safe scripts
and the support-files init scripts..
