linux: use IORING_OP_FTRUNCATE when available (#4554)
Route ftruncate() system calls through io_uring instead of the thread
pool when the kernel is new enough to support it (linux >= 6.9).
This commit harmonizes how libuv checks if the kernel is new enough.
Some ops were checking against `uv__kernel_version()` directly while
others stored the result of the version check as a feature flag.
Because the kernel version is cached, and because it is more direct
than a feature flag, I opted for the former approach.
