git: raise hard version to 1.7.9

Debian 6 Squeeze went EOL in Feb 2016.  We don't need to carry support
for that anymore as there have been 6 major releases since.  That means
we can bump the required git version from 1.7.2 to 1.7.9.  Ubuntu Precise
shipped with the latter.

git-1.7.2 was released in 2010 while git-1.7.9 was released in 2012.
So that shouldn't be a problem either.  And we've been warning people
using git versions older than 1.9.1 for 3 years now that they need to
upgrade.
