[mako] wlan firmware reload

mako needs to be able to reload wlan firmware. It's safe to keep these
file names (droid-wlan-fwreload.*) and hardcoded values (WCNSS_qcom_wlan_nv.bin,
wlan0) in, because everything is under device-lge-mako-configs folder.

In case another device needs to provide own fw reloader (i9305 doesn't need that),
it will suffice to move only droid-wlan-fwreload.service to device-configs-all/

More info:
WLAN driver on mako is built-in module, and needs external trigger
to re-read firmware once it's in place by conn_init service.

On Android, WLAN firmware reloader logic is in WifiStateTracker.java

Add os-release.d/hw-release to complement os-release. It will eventually be merged into /etc/os-release using oneshot or similar.

This is symlinked to /etc/hw-release for now to work with qdeviceinfo_linux.cpp which uses QStringList releaseFies = QDir(QStringLiteral(""/etc/"")).entryList(QStringList() << QStringLiteral(""*-release""));

Begin using tmp/ for built files to keep things clean

Use tmp/ for all transient build artefacts
