test: skip strace test with shared openssl

`parallel/test-strace-openat-openssl` was added to check explicitly
for a list of known files that would be opened for a set workload
(`require("crypto")`). This is not reliable when Node.js is linked
to an external/shared OpenSSL library (e.g. it might be configured
to load configuration files from a different default location and/or
load more than one configuration file) so skip this test when Node.js
is built in that way.
