stdint: fix definitions of minimum limits of exact-width integer types

[lukileczo]

JIRA: RTOS-872

Description

Fix the definitions of minimum limits of exact-width integer types. Previous version caused the compiler to assign the value 9223372036854775808 type unsigned long long and not long long as requested by the LL suffix - in which it would not fit - which caused warning.
