liburing v2.2 provides support for initialization of rings with "big"
submission and completion entries. Big entries allow embedding NVMe
submission and completion entries in the io_ring sqe/cqe and thereby an
enabler of "io_uring_cmd".
xNVMe utilizes the above. xNVMe v0.4.0 "vendored"/bundled liburing 2.2.
However, the bundling of liburing inside the xNVMe library is removed in
v0.5.0 to avoid linker issues. Instead, xNVMe v0.5.0 links liburing on
the system with discovery via pkg-config.
Thus, this change to update the liburing pkgdep to v2.2, in preparation
for upgrading the xNVMe submodule to v0.5.0.
