CMakeLists: Refer to libdrm-amdgpu1 for RPM distros

The infra is in place to make sure that we can get around the issue
where older versions of rpm don't know what "Suggests" is. Using the
HSAKMT_REQUIRES_LIBDRM variable will force the package to require
libdrm-amdgpu1 instead of just suggesting it in newer distros.
