PulkoMandy 32a71a00aa stdint.h: fix definition of UINT8_MAX, UINT16_MAX, UINT8_C and UINT16_C
C99 chapter 7.18.2, Limits of specified-width integer types:

"This expression shall have the same type as would an expression that is
an object of the corresponding type according to the integer promotions."

C99 chapter 6.3.1.1:

"If an int can represent all values of the original type, the value is
converted to an int; otherwise, it is converted to an unsigned int.
These are called the integer promotions."

Therefore, UINT8_MAX, UINT16_MAX, UINT8_C and UINT16_C should be signed.

This prevents building WebKit with -Werror.
