[libgomp, nvptx, --without-cuda-driver] Don't use system cuda driver
Using libgomp configure option --with-cuda-driver=<dir> we can indicate what
cuda driver to use to build the libgomp nvptx plugin. Without such an option,
the system cuda driver is used, if available. If not availabe, a dlopen
interface is used instead.
However, when we use --without-cuda-driver (or the equivalent
--with-cuda-driver=no) the system cuda driver is still used if available.
This patch fixes that, making sure that --without-cuda-driver selects the dlopen
interface.
Build on x86_64 with nvptx accelerator and tested libgomp testsuite, with and
without option --without-cuda-driver.

* plugin/configfrag.ac: For --without-cuda-driver, set
CUDA_DRIVER_INCLUDE and CUDA_DRIVER_LIB to no. Handle
CUDA_DRIVER_INCLUDE == no and CUDA_DRIVER_LIB == no.
* configure: Regenerate.
