[PATCH] lib: framework: log the fwts command line for reference.

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Since CERT may be running fwts with options that may be silently
ignoring some fwts errors it makes sense to also log the command
line options being used so we can see how fwts is being invoked
for reference purposes.
