hybris/lxc-android: updated and patched config for the latest lxc version

The config file for container from Halium repo is outdated, and will not load on latest version of LXC, here is the error when you start the container:

postmarketos:~$ sudo lxc-start android
lxc-start: android: confile.c: parse_line: 2447 Unknown configuration key "lxc.rootfs"
lxc-start: android: parse.c: lxc_file_for_each_line_mmap: 142 Failed to parse config file "/var/lib/lxc/android/config" at line "lxc.rootfs = /var/lib/lxc/android/rootfs"
Failed to load config for android
lxc-start: android: tools/lxc_start.c: main: 264 Failed to create lxc_container

This pull request updates the config file, but also use the latest commit.
