kfdtest: Fix gfx_target_version Parsing Issue

The purpose of this patch is to fix an issue in the run_kfdtest.sh
script's gfx_target_version parsing.

When the character length of the "gfx_target_version" value is
equal to 5 instead of 6, it will now be zero padded on the left to
allow each Major/Minor/Stepping value to be parsed correctly.

Also, kfdtest.exclude file now replaces the default filter for
aqua_vanjaram with the following 3 gfx filters:
gfx940, gfx941, & gfx942
