update linux-sun-j{dk,re}17 to update 60

[Koichiro IWAO]

Would you please update linux-sun-jdk17 to update 60?
linux-sun-jdk17 port says:

===>  linux-sun-jre17-7.55 You must manually fetch the J2SE RE download
for the Linux platform (jre-7u60-linux-i586.tar.gz) from
http://www.oracle.com/technetwork/java/javase/downloads/index.html,
place it in /usr/ports/distfiles and then run make again.
*** Error code 1

but jdk-7u55-linux-i586.tar.gz is unavailable. Only the latest
jre-7u60-linux-i586.tar.gz is available on the Oracle site.
