[BUG] macOS CI: sim:lua doesn't link with pipe2()

[lupyuen]

Description / Steps to reproduce the issue

sim:lua in macOS CI doesn't link with pipe2(). Is there something special about the Lua Build that fails with pipe2()? We may need to disable the build for macOS CI because NuttX Mirror Build is failing twice daily:

• CI: Disable the failed macOS Builds #14772

From sim-02 macOS Log: https://github.com/NuttX/nuttx/actions/runs/11825497334/job/32949471137

Configuration/Tool: sim/lua
ld: Undefined symbols:
  _pipe2, referenced from:
      _main in nuttx.rel
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [nuttx] Error 1
make: *** [nuttx] Error 2
make: Target `all' not remade because of errors.

please try CONFIG_PIPES=y, @lupyuen

@xiaoxiang781216 Yep it compiles OK on macOS Arm64 yay! But wonder if it's supposed to Seg Fault?
