replace dependency upx with upx-ucl for Debian|Ubuntu|LinuxMint from Kevin's patch, upx is too general, thanks kevin.
fixed for issue #7221(get files with/without copyright and with/without specific copyright)
fixed for #6015(Upgrade cp2foss to allow upload from a source repository). it is weird I did not find this defect.
changed test_fo_copyright_list.php because fo_copyright_list is changed to support show files with/without (specific) copyright.
