[Buildroot] [PATCH 1/1] dependencies.sh: Check for a host python version >= 2.7

[aduskett at gmail.com <aduskett@gmail.com>]

From: Adam Duskett <Aduskett@gmail.com>

Older distributions such as CentOS6 come with python2.6, which causes build
failures in packages such as host-libglib2 because they require python2.7 or
above.

CentOS6 does have the centos-release-scl which allows users to install
python2.7, making this transition reasonably easy.

Debian 6 and 7 have reached EOL, and Debian 8 comes with Python 2.7, so
this patch should be relatively low impact.
