devdraw: fix title and "open in top" on OS X

On OSX 10.10, when you open an application that depends on devdraw, the
title bar only shows the first letter of the application's name. The
patch sets a default title as soon as the window is created, which
fixes this issue.

On OSX 10.10, when you open an application that depends on devdraw, this
application is opened in top of other windows, however the menu bar is
not updated. The patch calls topwin() at the end of makewin() in
src/cmd/devdraw/cocoa-screen.m .

9pfuse: Disable glibc workaround for O_LARGEFILE on ARM

9pfuse fails on ARM when O_LARGEFILE is supported.
glibc does define O_LARGEFILE properly on ARM,
and the value is different than what that this workaround suggests,
causing it to wrongly detect bad flags.
