nsswitch: fix wbinfo -m --verbose trust type "Local"

Remove wrong "Local" strcmp(), there's another one, the correct one, a few lines
below. Since commit 95e3307917b5731ab883ee5fce530c5b559b4934
WBC_DOMINFO_TRUSTTYPE_NONE, which corresponded to the string "None" in the
winbindd response, is not used anymore.
