RISC-V: Force scalable vector on all vsetvl tests

RISC-V: Force scalable vector on all vsetvl tests

Since when VLEN = 128bits and FIXED-VLMAX, vsetvli a5,zero will be optimized
into vsetivli zero, 16 for SEW = 16.
Such situation will cause many bogus FAILs in FIXED-VLMAX of full coverage
testing.

Force them all scalable vectors to supress those bogus FAILs.
