tests/cc: Fix type of constant in 0253-maxconst.c

If a decimal integer constant has no suffix, its type is the first
of [int, long int, long long int] that can represent it[0]. The
value 18446744073709551615 (2^64 - 1) cannot be represented in any
of those types. Instead, use 18446744073709551615u, which can be
represented as `unsigned long long int`.

[0] See C99 6.4.4.1p5
