Add a new variable to let fish know that -- since the parent commit
-- we are running a version where fish can use the kitty keyboard
protocol without breaking mc.
In a few years, both fish and mc should ideally remove this hack
(and fish should speak the kitty keyboard protocol unconditionally),
so no one should rely on this new variable except as a temporary
workaround. Hence the feature-specific flag and not a generic version
variable.

If a subshell (like fish 4.0) wishes to use "Disambiguate control keys"
from https://sw.kovidgoyal.net/kitty/keyboard-protocol/, ctrl-o sends
a multi-byte sequence. Let's make sure we can intercept that too so
we can suspend the shell.
Note that the shell already disables "Disambiguate control keys"
while it's suspended, so no other changes should be necessary.
Unfortunately there is one bug left: when I start "SHELL=$(which
fish) mc" and type `ctrl-o`, fish does not recognize CSI u bindings
(such as `bind ctrl-2 'echo hello'`) yet. It only works after the
second prompt. I haven't had time to figure that out.

Non-XPG4 version of `tail` fails if you call it as `tail -n 1`, but `tail -1`
works everywhere and is portable.

Non-Linux systems don't always name the user and group with uid/gid of 0
"root". On macOS group "wheel" has gid of 0 and group "root" doesn't exist. On
FreeBSD there is a user with gid of 0 named "toor". This causes user/group id
lookups in mc to fail and instead return the uid/gid of the current user.
