acme: split win into winfs and rc script, get rid of lib9p leavefdsopen hack

split the acme win command into a winfs fileserver which
handles /dev/cons emulation and a rc script responsible
for launching the command.

with these changes, the fd fiddling is not neccesary anymore
and we can get rid of the leavefdsopen hack.
