MdePkg/BaseSafeIntLib: clean up parentheses in MIN_INT64_MAGNITUDE

The definition of the MIN_INT64_MAGNITUDE macro is correct, but it's
harder to read than necessary: the sub-expression

      (( (UINT64) - (MIN_INT64 + 1) ))

is doubly parenthesized. Reusing one pair of the outer parens, rewrite the
sub-expression (without change in meaning) so that the minus sign cannot
be mistaken for subtraction:

      ( (UINT64)(- (MIN_INT64 + 1)) )

The resultant macro definition matches the following expressions in
SafeInt64Mult():

>     //
>     // Avoid negating the most negative number.
>     //
>     UnsignedMultiplicand = ((UINT64)(- (Multiplicand + 1))) + 1;

and

>     //
>     // Avoid negating the most negative number.
>     //
>     UnsignedMultiplier = ((UINT64)(- (Multiplier + 1))) + 1;
