lavf/mpegtsenc: Add parentheses to clarify operator precedence in CC update

Browse Source 
While "cc + 1 & 0xf" is technically correct because addition has
higher precedence than bitwise AND in C, the intent of "(cc + 1) & 0xf"
is not immediately obvious without recalling the precedence table.

Add explicit parentheses to make the intended evaluation order clear
and improve readability.
