[debian-mysql] Bug#981905: mysql-8.0: missing runtime dependency on -dev package

[Gianfranco Costamagna]

Source: mysql-8.0
Version: 8.0.23-1
Severity: serious
tags: patch

Hello, the dev package exposes zstd build flags, but doesn't depend on it.
e.g. you can see boinc build log failing

checking mysql libraries... -L/usr/lib/x86_64-linux-gnu -lmysqlclient -lpthread -lz -lzstd -lm -lrt -lssl -lcrypto -ldl -lresolv
checking mysql includes... -I/usr/include/mysql

this patch should do the trick
