perf: make perf.run-limits code work with Python 3

We need b'' because perf.py isn't run through the source
transformer.

We need to cast the exception to bytes using pycompat.bytestr()
because ValueError can't be %s formatted due to built-in exceptions
lacking __bytes__.

We need to pycompat.sysstr() before the float() and int() cast
so the ValueError message doesn't have b'' in it.

Even with that, it looks like the error message for the ValueError
for float casts added quotes, so we need to account for that in test
output.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
