board_status/getrevision.sh: Ignore non-annotated tags

Local tags (e.g. to keep track of builds) should not be used to describe
a board status report. This has happened in some cases, e.g. [1].

According to the Git 2.41.0 manual for git-describe, the '--tagged'
parameter is a way to also use any "lightweight (non-annotated) tag" in
addition to annotated tags, which are always used even without this
parameter. All coreboot release tags seem to be annotated, so this
option should be safe to drop.
