[Buildroot] [PATCH] can-utils: add dependency on NPTL

[yegorslists at googlemail.com]

From: Yegor Yefremov <yegorslists at googlemail.com>

canfdtest.c assumes that clock_nanosleep() is always available. But it
is only available with NPTL. Since it unconditionally uses it, we add
dependency on NPTL.

Fixes:
