libcamera: v4l2_videodevice: Don't use std::atomic specialization
The std::atomic_uint64_t specialization was missing from C++14, and only
added to C++17 (see LWG 2441). It was treated as a Defect Report and
backported to earlier C++ standards by gcc and clang, but is missing
from libstdc++ shipped with gcc 5 and gcc 6. Fix the compilation error
by using std::atomic<uint64_t> instead.
Fixes: 4e0d1eca10b7 ("libcamera: V4L2BufferCache: Improve cache eviction strategy")
