[WIP] [SPARK-17421] Don't use -XX:MaxPermSize option when Java version >= 8
## What changes were proposed in this pull request?
Modifies the `build/mvn` and `build/sbt-launch-lib.bash` scripts so that
they check the Java version and omit the `-XX:MaxPermSize=512M` option for Java
versions >= 8.
## How was this patch tested?
Ran the build on Linux and Mac with Java 7 and 8, from `build/mvn` and
`dev/run-tests`. Also tested Java 8 with `JAVA_7_HOME` pointing to a Java 7
installation.
Currently, `dev/run-tests` has a few remaining instances of the MaxPermSize
warning, apparently due to another code path to spawning a JVM. Keeping this PR
as a WIP until the output of `dev/run-tests` is completely clean.
