kde/spacebar: improve APKBUILD (!979)

Stop manually making the build dir in a custom prepare() function, but
rather use the CMake -B argument to automatically make this directory.

[ci:skip-vercheck]: since this doesn't change the resulting package
compared to our previous APKBUILD a pkgrel bump is not necessary.

[ci:skip-build]: already built successfully in CI
