According to
https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getforegroundwindow
GetForegroundWindow can return nil in some circumstances. So
GetForegroundWindow cannot be used in the TestGetKeyboardLayout.
Just delete the test for now.

Some constants were removed in CL 600516 that included changes for the
Linux kernel 6.10.

This kernel version moved C defines to an enum ethtool_header_flags that
was not picked up by the mkall.sh script.

For enums, there is a perl script that needs to be run manually, and the
output must be added by hand to the list of constants in unix/linux/types.go.

See https://elixir.bootlin.com/linux/v6.10.3/source/include/uapi/linux/ethtool_netlink.h#L120
