build-sys: invoke ninja with -d keepdepfile

Browse Source 
After reading the dependency file, ninja just deletes it, in the name
of cleanliness I guess.  However this complicates debugging unnecessarily
compared to good old "-include *.d".  Use the keepdepfile debugging
option to make it easier to see what is going on.
