hg: build-infra/jdk7: Did a small optimiziation for the infamous grep command. The total list of packages is often in the hundreds, while the list of dependencies for a single package does not exceed 50 and is often very low. Grep works more effectively with few patterns and lots of text to search through, so I switched the arguments.
