RISC-V: Set the ABI for the RVV tests

The RVV test harness currently sets the ISA according to the target
tuple, but doesn't also set the ABI.  This just sets the ABI to match
the ISA, though we should really also be respecting the user's specific
ISA to test.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/rvv.exp (gcc_mabi): New variable.

(cherry picked from commit e6b050da8a4513ab37fd3699c7a963421fbe4d81)
