kernel: Calculate HASH and DIRTY in the same way as pkg/package.mk

Browse Source 
The definition of `$(TAG)` differs from pkg/package.mk and is only the
HASH+DIRTY since the full tag is defined by the kernel macro and varies for
each kernel.

Also `show-tag` is `show-tags` here due to the multiple builds. Individual
`show-tag_FOO` rules are provided similar to the `build_FOO` rules.
