[client] Fix 3 issues for the cost of one CL

- swarming.py reproduce uses a cache by default to fix usage on 32 bits.
- swarming.py reproduce cleans up 'work' directory by default.
- isolateserver.py uses a cache by default to fix usage on 32 bits.

Sorry for lack of tests, I burned all my energy on the last CLs so there was
none left. In practice, people who use these report bugs when they fail, so yay?
