io_uring is not supported on 4.14 hosts. Since firecracker-microvm#4689 dropped support for 4.14 hosts, and 5.10 does support io_uring, remove various checks related to unsupported (4.14) host kernels. Signed-off-by: Patrick Roy <roypat@amazon.co.uk>

Since firecracker-microvm#4689 dropped support for 4.14 hosts, and 5.10 does support io_uring, remove various checks related to unsupported (4.14) host kernels. Also update some of our unittests to always test both the sync and async block engines. Previously, we only tested the sync engine on 4.14 hosts, and only the async engien on 5.10 hosts. With the removal of 4.14 hosts, this meant that we were no longer unittesting the sync engine in these tests at all. Thus, have all the tests unconditionally test both engines.
