locale: avoid segfault freelocale()
PR 4964
Eric Nadler writes:
It looks to me like the base structure is not fully initialized
with 0 (only a subset of the structure is initialized).
This later results in a free of base->collate.index2weight in
_locale_set_l.
This free tries to free uninitialized memory and segfaults.
