    coredump: use unaligned_read_ne{32,64}() to parse auxv
    
    Fixes a bug introduced by 3e4d0f6cf99f8677edd6a237382a65bfe758de03.
    
    The auxv metadata is unaligned, as the length of the prefix
    "COREDUMP_PROC_AUXV=" is 19. Hence, parse_auxv{32,64}() may triger
    an undefined behavior (or at least cause slow down), which can be
    detected when running on an undefined behavior sanitizer.
    
    This also introduces a macro to define `parse_auxv{32,64}()`.
    
    Fixes #26912.
