Disable LTO in PKGBUILD to fix vendored Lua static link

Browse source 
makepkg's default -flto=auto made mlua's vendored liblua5.4.a contain GCC
LTO bitcode that the Rust (lld) link couldn't read, leaving all lua_*
symbols undefined. options=(!lto) produces a clean static link.
Verified building in a clean archlinux container.
