Title: oraclejdk: bump to 8u25, 7u71, and 7u72

Updates Oracle JDK 7 and 8.

From this version, Oracle provides two versions of JDK 7.

- JDK 7u71 is a Critical Patch Update (CPU) containing security and critical bug fixes.
- JDK 7u72 is a Patch Set Update (PSU) containing fixes of the CPU as well as non-critical fixes.

They says "Oracle strongly recommends that all Java SE users upgrade to the latest CPU release available for a release family. Most users should choose the CPU release."

oraclejdk7 is the CPU package. I added oraclejdk7psu for PSU version.
