package/igt-gpu-tools: needs NPTL threads

With classic thread library, the build fails with:

../lib/igt_kmod.c:1090:21: error: implicit declaration of function 'pthread_mutexattr_setrobust'; did you mean 'pthread_mutexattr_settype'? [-Werror=implicit-function-declaration]

igt-gpu-tools needs NPTL threads.
