lldpd: use release tar instead of codeload

lldpd: use release tar instead of codeload

There is currently a problem with making reproducible version of lldpd.
The tool version is generated based on 3 source:
1. .dist-version file in release tar
2. git hash with presence of .git directory
3. current date

Using the codeload tar from github results in getting the repo without
the .git directory and since they are not release tar, we don't have
.dist-version. This results in having lldpd bin with a version set to
the current build time.

Switch to release tar so that we correctly have a .dist-version file and
the version is not based on the build time.
