avfilter/asrc_sine: increase frequency accuracy

Previously the delta phase was fixed point fractional with 2^{32 fractions,
which caused inaccuracies in the output frequency, unless the input
frequency*2}32 was divisable by the sample rate.

This patch improves frequency accuracy by tracking subfractions of the delta
phase fractions. For this we are using a denominator which is a multiple of the
sample rate, making sure that integer frequencies are always accurately
represented.
