Let the live Hyprland session fall back to software rendering

Browse source 
On GPU-less targets (VMs, headless, exotic hardware) wlroots refuses to
initialise without a hardware renderer, so the autologin session exec'd
Hyprland on tty1 and it died immediately — leaving a blinking cursor and
no desktop, while tty2 still showed the (correct) `bos` login.

Export WLR_RENDERER_ALLOW_SOFTWARE=1 before exec Hyprland in root's
.bash_profile so wlroots may use the llvmpipe software renderer when no
GPU renderer exists. On real hardware the hardware renderer is still
chosen; this is purely a fallback. Also set WLR_NO_HARDWARE_CURSORS=1 so
the pointer isn't invisible in VMs. Both must be real env vars (read at
wlroots init), not Hyprland `env=` lines, which apply too late.

# without a GPU (VMs, headless, exotic hardware). On real hardware wlroots

# wlroots reads it at renderer init, earlier than any Hyprland `env=` line.
