Do not take address of va_list variable

This breaks on x86_64, where it is an array and thus gets bogus results.

* ddb/db_output.c (db_printf, kdbprintf): Pass copy of va_list variable instead
of its address.
* kern/debug.c (panic, log): Likewise.
* kern/printf.c (vprintf, iprintf, sprintf, vsnprintf): Likewise.
(_doprnt): Take va_list instead of va_list *, fix usage and comment accordingly.
* kern/printf.h (_doprnt): Take va_list instead of va_list *.
