[PATCH] kbuild: add sys_* entries for syscalls in tags

[Rabin Vincent]

Currently, it is no longer possible to use the tags file to jump to
system call function definitions with sys_foo because the definitions
are obscured by the use of the SYSCALL_DEFINE* macros.

This patch adds the appropriate option to ctags to make it see through
the macro.
