Per the APKBUILD reference, , package *-install scripts should be checksummed to guard against incomplete/corrupt downloads. The postmarketos-base package is one example where this is not being implemented currently.
Having it in boot doesn't actually work, the service is being started
too early and fails. This change moves it to the default runlevel. This
change also removes "wifi-handler" since that service doesn't actually
exist.
This updates the linux-postmarketos kernel to 4.12.4, and fixes an issue
where the APKBUILD was pulling down the 4.12 source but not the 4.12.x
patches. I think that pulling down the major.minor source and a sep.
package for patches to update to the major.minor.minor(er?) release adds
unnecessary complexity since kernel.org already hosts the sources with
these patches applied (e.g. in this case the 4.12.4 source)
