samsung-klte: add audio support for libhybris adaptation; some quality of life changes

• move msm-fb-refresher dependency to downstream kernel package, it is useless on mainline kernel

• disable msm-fb-refresher service when using libhybris adaptation, it is only required for downstream kernel without libhybris. It interferes with qcom kgsl-adreno driver badly (causes screen flickering)

• set CPU governor to conservative on system startup (it lowers CPU frequency in idle state from initial 2.4 Ghz to 300 MHz)

• add hybris_pulse subpackage that gets installed only when device-samsung-klte-hybris AND pulseaudio are installed. It pulls in pulseaudio-modules-droid-7.1-caf and alsa integration

• add system.img symlink to lxc-android installation. With this you can have Android container successfully running already at the first boot without need to do it manually. Halium installation process puts your system.img to /data partition by default, so follow their recommendation. We can use a symlink to save some space on /system partition.

added category::device + 1 deleted label

Awesome work! I can't test it as I don't have the device, but the changes look good. I like that you think of all the options (downstream without libhybris, downstream with libhybris, and mainline) as well. from me.

I tested (old video, but nothing has changed since then regarding audio support in libhybris)

GPU 3D acceleration (kwin_wayland-hwcomposer) is still a problem though, but one problem at a time

CI is failing, because gitlab's tarball downloads are currently broken. I'll change CI to use "git clone --depth=1" instead for now, to install pmbootstrap (new MR).

@minecrell also noted that we might want to use stable instead of master, but that needs further discussion and we did not found it important enough to have a proper issue about it. if somebody feels otherwise, please open a new issue with that topic and present your case.
