nvgpu: Get rid of NV_BUILD_KERNEL_OPTIONS for identify stable kernel

Browse Source 
There are some configs which are set for the stable kernel and
it is identified from the NV_BUILD_KERNEL_OPTIONS.

The stable kernel build nvgpu as out-of-tree module and
pass the environment config CONFIG_TEGRA_OOT_MODULE during
build.

Hence, it is not required to use the NV_BUILD_KERNEL_OPTIONS to
identify the kstable build. It uses CONFIG_TEGRA_OOT_MODULE for
setting the configs for build as module.
