Serial was driver was not being built if there is no console
device. Obviously, the serial driver may be needed even in
this case.
* arch/arm/src/stm32/stm32_serial.c: If there is a serial console,
it would be ttyS0 and the others would be ttyS1-5. If there
is not serial console, was labeling them ttyS1-6; now labels them
ttyS0-5.
* fs/fs_syslog.c: Can't handle SYSLOG output to character device from
the IDLE task (because it can't block). syslog_putc now returns EOF
on failure and sets errno. Fixed some errors in error handling.
* libc/stdio/lib_syslogstream.c: Checking of return value from
syslog_putc was bogus. Switching to EOF for all errors solves
this.
