vt: selection: take screen contents from uniscr if available
This preserves whatever was written even if we can't currently display the
given glyph. Mouse paste won't corrupt any character of wcwidth() == 1
anymore.
Note that for now uniscr doesn't get allocated until something reads
/dev/vcsuN for that console, making this code dormant for most users.
