libcamera: pipeline: ipu3: Fix compilation on gcc 5 and 6

Browse source 
Commit 5e7c5d64a6 ("libcamera: ipu3: Do not unconditionally queue
buffers to CIO2") introduced usage of the std::queue default constructor
by using copy-list-initialization from {}. The default constructor was
explicit in C++11, which was fixed retroactively with a defect report
(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0935r0.html).
gcc 5 and 6 are unfortunately affected, requiring explicit usage of the
constructor.
