fate-filter-hls-append test fails if system time is not set

[James Cowgill]

Summary of the bug:
The fate-filter-hls-append test fails if the system time is not set (ie it's around 1970 on unix).

How to reproduce:

$ sudo date -s '1971-01-01'
# or
$ sudo apt install faketime
$ NO_FAKE_STAT=1 faketime '1971-01-01' $SHELL
# then
$ make fate-filter-hls-append V=1

Results:
All the timestamps are incorrect. The exact timestamps given depend on the system time.

I notice that fate-filter-hls-append passes -af asetpts=RTCTIME to ffmpeg which is clearly going to depend on the system time - I don't think tests should be doing that.
