build: image: use printf for ModelNameLimit16 
Fix syntax error on macos, for substr is undefined results according to
the POSIX standard.

From expr on macos:
 According to the POSIX standard, the use of string arguments length,
 substr, index, or match produces undefined results.  In this version of
 expr, these arguments are treated just as their respective string values.

By a simple test Makefile:

define ModelNameLimit16
$(shell expr substr "$(word 2, $(subst _, ,$(1)))" 1 16)
endef

define ModelNameLimit16_2
$(shell printf %.16s "$(word 2, $(subst _, ,$(1)))")
endef

hello:
	echo $(call ModelNameLimit16, technicolor_tg582n-telecom-italia)
	echo $(call ModelNameLimit16_2, technicolor_tg582n-telecom-italia)

The same output is produced.

echo tg582n-telecom-i
tg582n-telecom-i
echo tg582n-telecom-i
tg582n-telecom-i
