Concatenate all components in the last line instead of accumulating
them into the 'res' variable.
No functional change is intended. A preparation for the next change.

* [PATCH 2/2] setlocalversion: use only the correct release tag for git-describe

Currently, setlocalversion uses any annotated tag for git-describe.
If we are at a tagged commit, it will not append the commit hash.
$ git checkout v6.2-rc1^
$ make -s defconfig kernelrelease
6.1.0-14595-g292a089d78d3
$ git tag -a foo -m foo
$ make -s kernelrelease
6.1.0
If a local tag 'foo' exists, it pretends to be a released version
'6.1.0', while there are many commits on top of it.
The output should be consistent irrespective of such a local tag.
Pass the correct release tag to --match option of git-describe.
In the mainline kernel, the SUBLEVEL is always '0', which is omitted
from the tag.
KERNELVERSION annotated tag
6.1.0 -> v6.1 (mainline)
6.2.0-rc5 -> v6.2-rc5 (mainline, release candidate)
6.1.7 -> v6.1.7 (stable)
To preserve the behavior in linux-next, use the tag derived from
localversion* files if exists. In linux-next, the local version is
specified by the localversion-next file.
