stats.lua: prevent freeze in certain cases with vidscale=no

Browse Source 
If using --script-opts=stats-vidscale=no, until osd-height changes from
0 to the correct value, stats.lua's text sizes are multiplied by a scale
of 720, which with the default font size results in a font size of 5760.
Depending on the order of operations, if the stats are drawn at this
size before osd-height is updated, mpv freezes. I get this with
--input-commands=script-message-to stats display-stats-toggle in
conditional profiles, e.g.:

mpv --script-opts=stats-vidscale=no --include=<(echo $'[test]\nprofile-cond=true\ninput-commands=script-message-to stats display-stats-toggle') av://lavfi:testsrc

Fix this by setting a scale to 1 until osd-height is updated to the
correct value.
