- Follow up fix for kernel version lookup

When using custom kiwi boot images a shell method named
baseCreateCommonKernelFile was used to create a common
kernel file name in the boot image to allow a simpler
search code in the builder. The search code in the builder
however uses the standard kernel naming schema and with
the latest changes to the kernel version lookup the
common name did not match the matching pattern anymore.
The use of such a common kernel file is obsolete and
the shell method can finally be deleted.

- Refactor kernel version lookup

For the lookup of the kernel version kiwi provided a small
C program that reads the first bytes of the kernel binary
and extracts the version information. Given the various
compression formats and also the problem of kernel files
that contains the decompressor code which could be anything
it has turned out to be difficult to provide a stable tool
to read the version from the binary. Therefore the code in
kiwi was refactored to read the version via regexp match
from the filename which also makes kversion an obsolete
tool. This Fixes #1308
