fix: set --openssldir=/etc/ssl so profiler finds system CA bundle (#18)

Without --openssldir, OpenSSL's compiled-in default cert search path is
/usr/local/openssl/ssl (based on --prefix), which does not exist on user
machines. SSL_CTX_set_default_verify_paths() finds no CAs and all HTTPS
profile uploads fail with "SSL server verification failed".

Same fix as grafana/pyroscope-dotnet@d5c4ca7
