console_simple: Fix compilation

Since fprintf and console_puts now return the number of
character written the prototypes have changes. We forgot
to fix console_simple which now fails to compile with:

common/console_simple.c:48:6: error: conflicting types for 'fprintf'
include/stdio.h:57:5: note: previous declaration of 'fprintf' was here
common/console_simple.c:67:6: error: conflicting types for 'console_puts'
include/stdio.h:20:5: note: previous declaration of 'console_puts' was here

Fix this by returning the proper numbers of characters written.
