mined1.c: remove i386 guard around escape sequences.

The escape sequences for the function keys used to be separated
out in older versions of Minix when they were different for m68k
and intel. Support for m68k was dropped and that code was
removed, leaving the ifdef i386. Since the sequences are the
same for i386 and arm, there is no need to keep the ifdef i386.
