This was pretty embarrasing bug, check for read-only status was reverted
in my changes for making Hatari GEMDOS HD emulation to behave more like
real TOS: none of the TOS versions enforce Fopen() read/write settings when
program does Fread/write calls, checking is only done at Fopen() call.

Testing it more was on my TODO list, but I hadn't gotten around to that
yet (I should have done that before commit, but I accidentally commited
it earlier with some other changes, as accidents like that are a bit
easier with hg than git).

Btw. When you have any GEMDOS HD emulation issues, best is to use
"--trace gemdos", it will tell right away what operation fails and why.
