unpack.c: Cast negative signed offset to signedHEADmaster
As N1570ยง6.5.16.2p3 states, E1 += E2 is equivalent to E1 = E1 + (E2). This means that E1 + (E2) will be subject to (6.5.6p4) "the usual arithmetic conversions". Since both types have equal integer conversion rank (6.3.1.1p1), E1 which was intmax_t will first be converted to uintmax_t before being added to (E2). This is not the intended result as it relies on integer wrapping behaviour again. Casting E2 to intmax_t first prevents the conversion of E1 and produces the correct result.
