mc146818rtc: Remove the hyphen to build on NetBSD and Darwin 

http://netbsd.gw.com/cgi-bin/man-cgi?date++NetBSD-current
The NetBSD manual tells us the date in NetBSD doesn't take any flags
to enable or disable padding in the format.

By default, date pads numeric fields with zeroes. This will convert the
number to octal one. So add "0x" to convert it to BCD directly.
