    Update the certificate files to make the test pass on Debian 10

    The old certificate files (for example, test/rubygems/ca_cert.pem) were
    signed by SHA1.  This message digest is considered too weak and rejected
    by OpenSSL 1.1.1 or later.  Because of this, the test suite does not
    pass on Debian 10.

    This change regenerates the files.
    A shell script for the regeneration (util/create_certs.sh) is also
    added.

    * remove trailing spaces.
