[media] v4l2: move tracepoint generation into separate file
To compile videobuf2-core as a module, the vb2_* tracepoints must be
exported from the videodev module. Instead of exporting vb2 tracepoint
symbols from v4l2-ioctl.c, move the tracepoint generation into a separate
file. This patch fixes the following build error in the modpost stage,
introduced by 2091f5181c66 ("[media] videobuf2: add trace events"):
ERROR: "__tracepoint_vb2_buf_done" undefined!
ERROR: "__tracepoint_vb2_dqbuf" undefined!
ERROR: "__tracepoint_vb2_qbuf" undefined!
ERROR: "__tracepoint_vb2_buf_queue" undefined!
