certs + private keys location is not in line with MRI

[mkristian]

/usr/lib/ssl$ ls -al
certs -> /etc/ssl/certs
misc
openssl.cnf -> /etc/ssl/openssl.cnf
private -> /etc/ssl/private

MRI seems to inherits this from openssl

currently things do follow this partially:

• for private keys it looks at /usr/lib/ssl/private
• cacerts it looks in $JAVA_HOME/lib/security/cacerts but not in /usr/lib/ssl/certs

ubuntu does link the /usr/lib/ssl/ files to /etc/ssl

so altogether jruby-openssl do use the openssl directories and just fall back on $JAVA_HOME/lib/security/cacerts if there is a not other cacerts.

that should be actually smt intended see b914091 ... and issues such as jruby/jruby#1953
