Subject: Test suite: use test/test_environment as busted helper

When parsing test options, instead of directly looking
for '-Xhelper' in arguments and splitting the next arguments on commas
add .busted config to set test/test_environment as busted helper.
Then busted will do the splitting on its own and set global arg to
split options.
