Subject: test/drb/test_drbssl.rb: skip LeakChecker as openssl keeps
 /dev/random

and /dev/urandom intentionally.  OpenSSL::PKey::RSA.new opens the two
random generators and keeps the file descriptors.

https://github.com/openssl/openssl/blob/93f99b681ab5a1cf7062053323e09b0cad5ff854/crypto/rand/rand_unix.c#L674

They are detected by the LeakChecker as fd leak, but it is intentional.
