[pseudo][PATCH] fcntl: Add support for F_GETPIPE_SZ

["Mike Crowe" <yocto@mac.mcrowe.com>]

When running the test suite on my Debian 11 box I see many occurrences
of:

 unknown fcntl argument 1032, assuming long argument.

(for example from test-execl.sh.)

It appears that this is F_GETPIPE_SZ and it takes no arguments. Let's
add it to avoid the warning messages.

I could add F_SETPIPE_SZ too, but that apparently takes an int argument
which would mean moving the va_arg call into the switch statement. :(
