[8u] RFR 8176182: 4 security tests are not run

[Aleksey Shipilev]

Original RFE:
  https://bugs.openjdk.java.net/browse/JDK-8176182
  https://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/9132102b7bb6

It does not apply to 8u cleanly, because:

test/sun/security/ec/SignedObjectChain.java:
 - copyright hunk already up to date

test/sun/security/mscapi/SignedObjectChain.java:
 - copyright hunk already up to date

test/sun/security/rsa/SignedObjectChain.java:
 - copyright hunk already up to date
 - @summary and @run lines was already modified by previous backport:
    https://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/ece6722932ca#l103.1

test/sun/security/ssl/rsa/SignedObjectChain.java:
 - copyright hunk already up to date
 - @summary line was already moved, but @run line is not there!
    https://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/ece6722932ca#l116.1

Testing: new tests run
