build: don't enable all kernel modules in the general OpenWrt .config With this change, there are two OpenWrt config files: one for the packages actually used by Gluon, and one with all kernel modules enabled (like it was since we removed the static kernel configs). The config with all kernel modules is only used to generate the kernel configuration (so it is compatible with the upstream kernel). This should bring the build times back to what they were before the static configs were removed.

Get rid of the static kernel configuration files With a backported patch from the OpenWrt trunk, it is now easy to generate an equivalent configuration using CONFIG_ALL_KMODS. The build will take a bit longer because all kernel module packages are actually built even when they are not included in the image, but adding new targets becomes a lot easier. Also, related documentation updates and fixes.
