app/test: fix misplaced braces in devargs check

This patch fixes two occurrences where a call to strncmp had the closing
brace in the wrong place. Changing this form:
	if (strncmp(X,Y,sizeof(X) != 0))
which does a comparison of length 1, to
	if (strncmp(X,Y,sizeof(X)) != 0)
which does the correct length comparison and then compares the result to
zero in the "if" part, as the author presumably originally intended.
