Mostly hacks for multiplying Frequency-type proxies by constants

(plus some small fixes).

python/m5/config.py:
    Hacks to allow multiplication on Frequency/Latency-valued proxies.
    Provide __rmul__ as well as __mul__ on Proxy objects.
test/genini.py:
    Default value for -EFOO should be True not 1 (since 1 is no longer
    convertable to Bool).
