[PATCH] disas: Replace straggling CS_ARCH_SYSZ

[Eric Farman <farman@linux.ibm.com>]

When updating to capstone v6, the define CS_ARCH_SYSZ was replaced
with CS_ARCH_SYSTEMZ, except here. On systems without capstone-devel
installed, this causes a compile error:

  ../disas/disas-host.c: In function ‘initialize_debug_host’:
  ../disas/disas-host.c:78:24: error: ‘CS_ARCH_SYSZ’ undeclared (first use in this function); did you mean ‘CS_ARCH_SH’?
     78 |     s->info.cap_arch = CS_ARCH_SYSZ;
        |                        ^~~~~~~~~~~~
        |                        CS_ARCH_SH
  ../disas/disas-host.c:78:24: note: each undeclared identifier is reported only once for each function it appears in

Rather than making capstone required, replace the constant
with the same one used elsewhere after that change.
