    sys/contrib/zlib: Always define Z_U8 and Z_U4
    This is a temporary hack for zlib to make sure that the library
    still builds when building with Z_SOLO (used in kernel and loader),
    as zlib is depending on limits.h which is only available in STDC
    PR:             kern/262977
    MFC after:      3 days
    (cherry picked from commit 0a21252adf11f7e839eabeb530e75cd1f9cd5386)
    Approved by:    re (gjb, early MFC)
