The variable 'NV_BUILD_SYSTEM_TYPE' is an NVIDIA internal Makefile variable used for building the Linux kernel. We should avoid using this in drivers where possible because otherwise it will require external users to set this. CONFTEST itself is not internal and is distributed with the NVIDIA OOT drivers. Rather than using 'NV_BUILD_SYSTEM_TYPE' to see if CONFTEST is presence, we can simply see if the 'srctree.conftest' variable is set and avoid using 'NV_BUILD_SYSTEM_TYPE' at all. Furthermore, given that the variable 'CONFIG_TEGRA_HWPM_CONFTEST' now defines if CONFTEST is present and this will only be set in the Makefile if 'CONFIG_TEGRA_HWPM_OOT' is set, then we don't need to check for both of these variables in the source files to determine if we need to include 'nvidia/conftest.h'.
