[PATCHv2 blktests] loop/011: skip if running on kernel older than v6.9.11

[Nilay Shroff <nilay@xxxxxxxxxxxxx>]

The loop/011 is regression test for commit 5f75e081ab5c ("loop: Disable
fallocate() zero and discard if not supported") which requires minimum
kernel version 6.9.11. So running this test on kernel version older than
v6.9.11 would FAIL. This patch ensures that we skip running loop/011 if
kernel version is older than v6.9.11.
