Disable the Atmos keyboard's CAPS LOCK for stdio too.

Normally, CAPS LOCK is active because the Oric Atmos's default programming language, BASIC, requires upper-case keywords.  It's turned off if cgetc() is used in a cc65 program.  When I added a console read(), I forgot to turn it off for that input also.  This patch fixes that oversight (better late than never).
Same consistency thing here. The comment you changed is present in the original form in about all ctr0.s's - if you consider it important enough to be changed please change all of them. This is more or less true for all comment changes in this ctr0.s
