media-libs/chromaprint: restore ffmpeg, unbundle gtest

update metadata : repo is on github, rm googletest

restore ffmpeg (bug 833821) if tools is enabled
remove definition for AUDIO_PROCESSOR_LIB because libavsamplerate is no
longer checked
for FFT_LIB, use avtx instead of avfft, removed in ffmpeg-8.0

remove 3rdparty :
unbundle gtest (and set gnu++17 for that)
remove kissfft, unused and with QA_CMAKE warn

rm custom multilib_src_test, unneeded to launch the testsuite
