tinfoil: add internal mode to build_file() function

In OE's devtool we want to repeatedly run build_file() without showing
unnecessary messages and triggering buildhistory for each call.
build_file() is just a wrapper around the buildFile command. Change
the final "hidewarning" parameter of the buildFile command to "internal"
and have this call a new buildFileInternal() function without triggering
any of the normal build events, silencing the normal info messages from
the runqueue ("Executing RunQueue Tasks", "Tasks Summary" etc.) and
avoiding calling parseConfiguration() which we've already done at this
point.
