[PATCH blktests 1/2] common/rc: add _have_kernel_options helper function

[Chaitanya Kulkarni]

Add a new helper function _have_kernel_options() that accepts multiple
kernel config options as arguments. This allows tests to check for
multiple kernel options in a single call, making the requires()
function more concise.

Example usage:
  requires() {
      _have_kernel_options IO_URING BLK_DEV_INTEGRITY
  }

Instead of:
  requires() {
      _have_kernel_option IO_URING
      _have_kernel_option BLK_DEV_INTEGRITY
  }

The function iterates through all provided options and returns failure
if any option is not enabled, maintaining the same error reporting
behavior as individual calls.
