Makes "silent" build quieter.

This suppresses all "success chatter" from the daemon regression tests
when building in --silent (or -s) mode.  Failing cases still output
the usual messages (except for "Processing...").  Other regression
chatter is still present, but this puts a big dent in it.

This involves three changes:

1) It adds a -q option to gpsfake, to suppress the "Processing"
messages.

2) It adds a -Q option to regress-driver, which passes -q to gpsfake
and also suppresses its own output in the success case.  Failure
output is unaffected.

3) It adds the -Q option to regress-driver invocations when the build
is running in silent mode.

TESTED:
Ran regress-driver in normal, -q, and -Q modes.
Ran "scons build-all check", with and without -s.
Also tested an error case with a garbled .chk file.
