reduce DELAY_MINIMUM_SLEEP_US to 100 by default

This makes flashrom sleep more eagerly rather than busy-waiting,
observing that most delays in flashrom are either less than 100
microseconds (barely enough time to get any work done, even on a fast
machine) or much more than 1 millisecond (very wasteful to busy-loop).
Since we believe most systems offer good timer resolution that should
provide sleep latency on the order of 100 microseconds, this is a
reasonable default.

For DOS, the default is set to 50ms because the best available timing
source on DOS only ticks at about 20 Hz.
