testsuite: [arm] Add missing effective-target to vusdot-autovec.c

This test fails when forcing an -mcpu option incompatible with
-march=armv8.2-a+i8mm.

This patch adds the missing arm_v8_2a_i8mm_ok effective-target, as
well as the associated dg-add-options arm_v8_2a_i8mm.

	* gcc.target/arm/simd/vusdot-autovec.c: Use arm_v8_2a_i8mm_ok
	effective-target.
