When GDB support is compiled in, halt() in libpayload will call
gdb_enter(). halt() is defined in <stdlib.h> and gdb_enter() in
<libpayload.h>. Usually files just include <libpayload.h> so this is not
a problem, but in some situatons a payload may just include <stdlib.h>
(or a file including it like <assert.h>), leading to an undeclared
identifier here. Move the GDB functions to <stdlib.h> to solve this.
