xtensa: Properly strdup string when building reggroup
I noticed this while looking at the reggroup intializations. It seems
for xtensa the "cpN" reggroup->name is getting assigned to the same text
pointer for each iteration of XTENSA_MAX_COPROCESSOR.
Note, internally reggroup_new() does not do any xstrdup().

* xtensa-tdep.c (xtensa_init_reggroups): Use xstrdup for cpname.
