tests: Get the packages for pkcs11 testing on the CI/CD system

Get the packages for pkcs11 testing on the CI/CD system, where available.
On those system where it is not available, skip the two tests.

The following distros cannot run the pkcs11 tests:

- Alpine: package with pkcs11 engine not available
- CentOS7: softhsm 2.1.0 is too old for tests to work; tests also fail when
           trying to sign with pkcs11 URI using openssl command line tool
- OpenSuSE Leap: softhsm package not available in main repo
