Hi.

This PR adds F_SEAL_EXEC, which is used to forbid future modifications of a file exec bit.
It was first added in kernel 6.3 1.

On a general way, do you think it could be possible to add a CI job reading kernel include/uapi/linux files to check if all the flags have a golang counterpart?

Best regards.
