_alpm_splitdep(): don't pass bogus length value to strndup

Browse Source 
If we fell through to the ALPM_DEP_MOD_ANY case, ptr would be NULL, and
we would pass (0 - <str>), which is a rather large negative number or
bogus positive number, depending on signed/unsigned. Just use strdup in
the case where we don't have a ptr available.
