Fix s390_kimd/kmld_shake inline assemblies

The KIMD and LKMD instructions update the source register pair during
processing. Declare the source registers as output registers and also
add the '+' constraint to them.

This fixes a segfault in the shake functions when libica is compiled
with clang on Ubuntu 22.04
