inttypes.h: add (some) iso c99 fprintf format specifiers

Skipped the specifiers for octal, (u)int_leastN_t, (u)int_fastN_t and
(u)intmax_t as we don't use them in rockbox

Specifiers use the types specified in stdint.h
Specifiers for short (16 bits) and char (8 bits) use the int specifier,
our format.c doesn't know about 'h' and 'hh'
