[PATCH] path-list.c: always free strdup'ed paths

["René Scharfe" <rene.scharfe@lsrfire.ath.cx>]

Always free .paths if .strdup_paths is set, no matter if the
parameter free_items is set or not, plugging a minor memory leak.
And to clarify the meaning of the flag, rename it to free_util,
since it now only affects the freeing of the .util field.
