termrc: setup mouse when we have a framebuffer

previously, we setup mouse only when vgasize= was specifid in
plan9.ini. with efi systems, the framebuffer is already setup
for us and theres no requirement for going thru aux/vga setup,
but we still want to setup the mouse.

so do the mouseport= check once theres a framebuffer by testing
the existence of '#i/winname' (which fails when thers no
framebuffer).
