ar71xx: fix mtdpartsize macro in image Makefile (#14961)

The mtdpartsize macro triggers shell errors on various Linux distributions
when the partname argument $(1) does not appear within the partmap $(2).

Change the sed pattern to only emit anything if a successful substitution
occured and only evaluate the arithmetic expression if something was printed
by the sed program.
