arm: MVE: Fix unintended change to tests

When committing my last patch I accidentally removed -mfpu=auto from the following tests. This puts it back.

testsuite/ChangeLog:
2020-04-03  Andre Vieira  <andre.simoesdiasvieira@arm.com>

	* gcc.target/arm/mve/intrinsics/mve_vector_float.c: Put -mfpu=auto back.
	* gcc.target/arm/mve/intrinsics/mve_vector_float1.c: Likewise.
	* gcc.target/arm/mve/intrinsics/mve_vector_float2.c: Likewise.
	* gcc.target/arm/mve/intrinsics/mve_vector_int.c: Likewise.
	* gcc.target/arm/mve/intrinsics/mve_vector_int1.c: Likewise.
	* gcc.target/arm/mve/intrinsics/mve_vector_int2.c: Likewise.
	* gcc.target/arm/mve/intrinsics/mve_vector_uint.c: Likewise.
	* gcc.target/arm/mve/intrinsics/mve_vector_uint1.c: Likewise.
	* gcc.target/arm/mve/intrinsics/mve_vector_uint2.c: Likewise.

Testing Done:
@IP: I assert this is almost no risk.
