Fix va_start related location
In gcc/testsuite/gcc.dg/pr30457.c, the first warning was not being
emitted because the relevant location was inside the var_start macro
defined in a system header. It can even point to a token for a
builtin macro there. This patch unwinds to the first token in real
source code in that case.
Tested on x86_64-unknown-linux-gnu against trunk.
* builtins.c (fold_builtin_next_arg): Unwinds to the first
location in real source code.
