[Piglit] [PATCH v3 2/7] piglit-run.py: Replace Piglit's --concurent flag with --no-concurrency

[Dylan Baker]

Since piglit defaults to using concurrency, and since concurrency is
generally the desired behavior, it seems more appropriate to have a flag
that turns off concurrency than one that takes an argument to set it on
or off.

V2: - Leaves --concurrency option, but marks it as deprecated
