[PATCH] avfilter/vf_frei0r: fix time not being passed in seconds

[Stefan Breunig]

The frei0r API expects the time in seconds, but was given it in
milliseconds. The bug might exist since 41f1d3a (~14 years ago),
but plugins depending on the time are unwatchable without this
patch. For example:

ffmpeg -filter_complex "testsrc2=d=5,frei0r=distort0r" out.mp4
