[perl #131263] clear the UTF8 flag on a glob if it isn't UTF8
Previously sv_2pv_flags() would set the UTF8 flag on a glob if it
had a UTF8 name, but wouldn't clear tha flag if it didn't.
This meant a name change, eg. if assigned another glob, from a UTF8
name to a non-UTF8 name would leave the flag set.
