GHA: Fix rockylinux:9 by install compression libs

Since recently, rockylinux:9 failed with linker errors against bz2, lzma
and zstd. Installing the relevant devel packages fixed the builds.

For reasons, cmake has started to add the -lbz2, -llzma, and -lzstd
linker flags. Since Icinga 2 usually does not need those, the relevant
devel packages were not installed. This may be due to some other
transitively linked dependency.

Hopefully, this issue may resolve itself in the near future, but for the
time being this satisfies our CI run on Rocky Linux 9.
