Preserve intermediate .c files in coverage mode

The introduction of the .y -> .c pattern rule causes some .c files such
as bootparse.c to be considered intermediate files in the .y -> .c -> .o
rule chain, which make would automatically delete.  But in coverage
mode, the processing tools such as genhtml need those files, so mark
them as "precious" so that make preserves them.
