zdev: Makefile: deduplicate *_usage.c generation

Browse Source 
Consolidate the duplicated sed command sequences used to generate
*_usage.c files into a shared CSTR_SED definition and a single pattern
rule:

	%_usage.c: %_usage.txt

This removes the copy/pasted rules for chzdev_usage.c and lszdev_usage.c
and keeps the Makefile easier to maintain.

Also drop the explicit chzdev.o/lszdev.o prerequisites on the generated
sources as dependencies are already tracked via the .*.o.d depfiles.
