[MFC Request] stand: Spell LUA_COMPILE_SET correctly.

[UEMURA Tetsuya]

Hi.

Main commit e63d20b70ee1dbee9b075f29de6f30cdcfe1abe1 corrected a typo in
stand/liblua/lutils.h, which the typo prevents my arm loader.efi,
specifically, loarder_lua.efi on RPi2 to boot. Can someone please MFC to
14-STABLE ?

Thanks in advance.
