Fix and improve kernel build when kerncache is enabled.

This patch gets rid of setting ROOT for merging kernel sources. Instead, the
sources are moved manually to the kerncache directory. A new file is created
containing the kernel version and it is fed into package.provided to prevent
merging the kernel sources again.
Brian Dolbec: fix whitespace error.
