[libc][NFC] Do not emit init / fini kernels in NVPTX libc 

Summray:
A recent patch upgrades the NVPTX ctor / dtor lowering pass to emit
kernels so other languages can call them. We do this manually in `libc`
so we do not need this. Use the provided flag to disable this step to
keep the created kernels cleaner.
