luajit2: fix build and runtime on powerpc

luajit2 currently fails to link for powerpc: lj_vm.o emits PLT calls
that force BSS-PLT, which the inline-PLT relocations emitted by GCC 12
and newer do not support. Add the same GOT-based fix that
lang/lua/luajit has carried as 060-ppc-musl.patch since 2019.

With that in place the package builds, but ipairs() and pairs() turn
out to be broken on 32-bit big-endian soft-float targets. Both are
regressions in luajit2's PPC64 patch and do not affect upstream
LuaJIT. To be submitted to openresty/luajit2 as well.
