Remove incorrect uses of __attribute__((__malloc__)).
xrealloc() is obviously incorrect, modern GCC docs even mention realloc() as an example where this attribute cannot be used. liblzma's lzma_alloc() and lzma_alloc_zero() would be correct uses most of the time but custom allocators may use a memory pool or otherwise hold the pointer so aliasing issues could happen in theory. The xstrdup() case likely was correct but I removed it anyway. Now there are no __malloc__ attributes left in the code. The allocations aren't in hot paths so this should make no practical difference.
