[PATCH] Makefile: respect $(V) in %.cocci.patch target

[Denton Liu <liu.denton@gmail.com>]

When the %.cocci.patch target was defined in 63f0a758a0 (add coccicheck
make target, 2016-09-15), it included a mechanism to suppress the noisy
output, similar to the $(QUIET_<x>) family of variables.

In the case where one wants to inspect the output hidden by
$(QUIET_<x>), one could define $(V) for verbose output. In the
%.cocci.patch target, this was not implemented.

Move the output suppression into the $(QUIET_SPATCH) variable which is
used like the other $(QUIET_<x>) variables. While we're at it, change
the number of spaces printed from 5 to 4, like the other variables
there.
