Deb: Match official Debian package libmariadb-dev-compat

Using this package any source that expects MySQL Client libraries should
build without changes. Sources that expect MariaDB Connector C should
build using only libmariadb-dev.

Current MariaDB Connector/C does not build quite identically in
this source tree compared to how it build in Debian official.
The remaining differences are tracked in MDEV-14921.
