libssp: Change __stack_chk_guard to uintptr_t

Browse Source 
Since the only test of __stack_chk_guard in GCC is declared as an integer:

 #ifdef __LP64__
 const unsigned long int __stack_chk_guard = 0x2d853605a4d9a09cUL;
 #else
 const unsigned long int __stack_chk_guard = 0xdd2cc927UL;
 #endif

and it is natural to assign an integer to __stack_chk_guard,

    c/c++: Declare stack protection guard as a global symbol

declared __stack_chk_guard as uintptr_t if it is an internal global
symbol.  Change __stack_chk_guard in libssp to match the internal
symbol type.

	PR c/121911
	* ssp.c: Include <stdint.h>.  Change __stack_chk_guard to
	uintptr_t.
