LINUX: Define printf/uprintf as variadic macros

Instead of defining the string 'printf' itself, make printf (and
uprintf) variadic macros. This avoids renaming printf to printk for
things like '__attribute__((format(printf,X,Y)))'.

Note that this is Linux-specific; compilers on other platforms may not
support variadic macros.

This avoids many warnings in the Linux kernel module build if we
include Linux headers after AFS headers.
