main/postmarketos-mkinitfs: set pmOS-specific firmware path

Currently we rely on the fact, that the kernel asks user space to load the firmware for it, so we can use the /lib/firmware/postmarketos directory for firmware.

As the kernel has support for loading the firmware itself since v3.7, and the parameter for adding an additional path to the search paths was added with v3.10, we can use that to not rely on CONFIG_FW_LOADER_USER_HELPER being set.

I wasn't aware of /lib/firmware/postmarketos for some reason, but I use firmware_class.path=/lib/firmware/<device> to have a device-specific firmware directory. This change would always replace my kernel parameter :)

What is the purpose of /lib/firmware/postmarketos? If it exists to avoid conflicting files with Alpine's linux-firmware packages, then having something like /lib/firmware/<device> would be preferable in my opinion to also avoid conflicts between device-specific firmware packages.

It looks like only one additional firmware directory can be set with this parameter, so maybe we could have a deviceinfo variable to change it?

@lambdadroid Yes, /lib/firmware/postmarketos gets used for non-linux-firmware firmware that is very likely device-specific.

I don't think it's worth changing a bunch of firmware apkbuilds to change that path - it works fine as it is. But you should be able to remove the firmware_class.path=/lib/firmware/postmarketos parameter on samsung-gts210ve* once this is merged.
