Fix RGBLINK failing to read args on certain machines
`char` has implementation-defined signedness, and if it's chosen to be unsigned,
then -1 gets converted to 255, which is then promoted back to `int` as... 255,
always failing the loop condition in src/link/main.c:118
`int8_t` has the correct signedness, but considering `musl_getopt_long_only`
returns `int`, better use that so as not to lose any bits
