xkb: strdup the values returned by XkbGetRulesDflts
XkbGetRulesDftls may get a copy of what will later be freed when passed into
XkbSetRulesDftls.
On the second run of XkbGet/SetRulesDflts:
XkbGetRulesDflts(rmlvo)
rmlvo->rules = current-rules
XkbSetRulesDflts(rmlvo)
free(current-rules)
current-rules = strdup(rmlvo->rules)
Leaving us with garbage in current-rules.
This patch requires callers of XkbGetRulesDflts to free the associated memory.
