[PATCH] RISC-V: Add missing torture-init and torture-finish for rvv.exp

[Kito Cheng <kito.cheng@sifive.com>]

Hi Vineet:

Could you help to test this patch, this could resolve that issue on our
machine, but I would like to also work for other env.

Thanks :)

We got bunch of following error message for multi-lib run:

ERROR: torture-init: torture_without_loops is not empty as expected
ERROR: tcl error code NONE

And seems we need torture-init and torture-finish around the test
loop.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/rvv.exp: Add torture-init and
	torture-finish.
