package/libqrencode: fix the _SITE package download url

The qrencode release archive is no longer distributed at [1].
This url now shows a HTTP/404 not found error.

The qrencode homepage [2] states:
"You can download the source packages at Releases[3] page at GitHub."

This commit updates the package download url to use github. The github
archive is not the same as the old release archive: it does not
contain the autotools configure script. For this reason, the hash
archive is updated and "_AUTORECONF = YES" is also added.

This commit also fixes the zbar runtime test [4] which is using
libqrencode to generate a qrcode to test zbar.

Fixes: [4]
