7.9 - release

[thezoggy]

• release link on website throws 404 (rpki-client-7.9.txt)

• github changelog has typo saying its 7.6 instead of 7.9 -- sent pull to fix

[Sebastian Benoit]

Hi, the 404 will be fixed momentarily, there was a permission error causing the txt file not to be synced to the ftp mirrors. The tar.gz was there though.

Updated changelog as well.
