Change unix_procs entropy source to be a plain EntropySource instead of
a Buffered_EntropySource. Data used in the poll is directly accumulated
into the output buffer using XOR, wrapping around as needed. The
implementation uses xor_into_buf from xor_buf.h
This is simpler and more convincingly secure than the method used
by Buffered_EntropySource. In particular the collected data is persisted
in the buffer there much longer than needed. It is also much harder for
entropy sources to signal errors or a failure to collected data using
Buffered_EntropySource. And, with the simple xor_into_buf function, it
is actually quite easy to remove without major changes.
