[Piglit] [RFC 9/9] backends/junit.py; use a unique replacement character for '.'

[Dylan Baker]

The problem with using '_' is that a lot of test names have '_' in them
(arb_ham_sandwich). By using something more unique ('?') we can
convert it back to '.' when transforming the junit result back into a
TestrunResult, which allows junit and json results to be compared in a
single summary.

I don't care at all what character we use. The only requirement is that
it must be unique (never show up in a single test). I originally
considered using "___", but was concerned that this might cause problems
with using the . regex to account for a single character, which ? would
solve.
