Fix consistently building of multiple arch

Browse Source 
We cannot build for another arch after building for one arch because of
setting skipBuild to true if one arch found. In other words "linuxkit
pkg build --platforms linux/riscv64,linux/amd64 ..." after "linuxkit pkg
 build --platforms linux/amd64 ..." will not build for linux/riscv64
 which is not expected.

In general when we check for available images and able to found part of
platforms we do not want to rebuild all of them. So this PR includes
platformsToBuild slice which we fill with platforms we want to build for
.
