speed up junit (issue 6250057)

[fel...@gmail.com]

Reviewers: metaweta, ihab.awad,

Description:
We're running junit with fork="yes" because we want the junit vm to
have different properties than the ant vm. However, we're spawning
a new vm for each junit test, which is unnecessary.

This adds forkmode="once" to the junit tests.

This reduces 'ant runtests' on my laptop from about 11 minutes to
about 7 minutes.
