[Buildroot] [PATCH 15/25] luaposix: fix runtime by selecting "bit32" instead of "bitop"

[Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>]

Since the bump of luaposix to 33.4.0, it doesn't work anymore at
runtime with LuaJIT or Lua 5.1. This can be tested with the following
defconfig:

BR2_x86_64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_PACKAGE_LUA=y
BR2_PACKAGE_LUA_5_1=y
BR2_PACKAGE_LUAPOSIX=y

/usr/bin/lua: /usr/share/lua/5.1/posix/init.lua:17: module 'bit32' not found:
...

In older luaposix versions, it would try to load the 'bit' instead of
'bit32' module if LUAVER == 5.1. However, this feature was removed in
33.4.0.

So instead of adding a runtime dependency on luabitop, depend on
lua-bit32.
