avcodec/lagarith: disable lag_decode_zero_run_line() and ask for a sample
The code seems to have never been tested
fixing it should be quite easy but needs a sample/testcase

configure: remove git url check
This part of the script doesn't check if git command is available and produce error if not.
It is 2 years since address changed and it is more reasonable to remove it than fix it.

INT_MAX is used here to denote the max allowed value for a sample format.
The opt-test code is changed to provide a valid reference example.
