    localedef: Use initializer for flexible array member [BZ #24950]

    struct charseq used a zero-length array instead of a flexible array
    member.  This required a strange construct to initialize struct
    charseq objects, and GCC 10 warns about that:

    cc1: error: writing 1 byte into a region of size 0
[-Werror=stringop-overflow=]
    In file included from programs/repertoire.h:24,
                     from programs/localedef.h:32,

    The change makes the object physically const, but it is not expected
    to be modified.
