also filter OpenSSL dependency in EasyBuild configuration for EESSI pilot 2023.04

[boegel]

In EESSI pilot 2023.04, OpenSSL 3.x is installed in the compat layer:

Apptainer> /cvmfs/pilot.eessi-hpc.org/versions/2023.04/compat/linux/x86_64/startprefix
Entering Gentoo Prefix /cvmfs/pilot.eessi-hpc.org/versions/2023.04/compat/linux/x86_64
$ openssl version
OpenSSL 3.0.8 7 Feb 2023 (Library: OpenSSL 3.0.8 7 Feb 2023)

In several easyconfigs included with EasyBuild, the wrapper module OpenSSL/1.1 is listed as a dependency, which leads to EasyBuild building OpenSSL 1.1.1 from source because the "system" OpenSSL can't be wrapped to fulfill OpenSSL/1.1.

To avoid this, we should simply filter out the OpenSSL dependency, and let EasyBuild rely on the OpenSSL provided by the compat layer.
