s390x regtest: Add missing memory clobbers in mvc.c

The s390x test case `mvc' was seen to fail when using gcc -O3 with GCC
11.4.1 on Ubuntu:

   mvc: mvc.c:48: main: Assertion `full[i] == 'x'' failed.

In this case the compiler optimized the assertion check away, because it
doesn't consider `full' to be affected by the inline assembly.

Add memory clobbers to fix this.
