Marton Balint 80e997b081 fate/filter-refcmp-*: make refcmp_metadata fail on empty or truncated input 
On empty input the awk script was always successful which caused the
filter-refcmp tests to always succeed.

Also fix the command lines for refcmp_metadata compare function because it
needs auto conversion filters, and update reference of test
filter-refcmp-psnr-rgb because it was missed in
a7fc78c1a6 but was never noticed due to the
original issue...
