[OE-core] [PATCH 05/13] buildhistory.bbclass: Improve the generated depends.dot file

[Peter Kjellerstedt]

* Convert incorrectly formatted dependencies such as:
    "bar -> "foo" ">=" "1.2.3"
  into dependencies with edge labels:
    "bar -> "foo" [label=">= 1.2.3"]
* Remove rpmlib() and config() dependencies such as:
    "foo" -> "rpmlib(CompressedFileNames)" [label="<= 3.0.4-1"]
  and:
    "base-files" -> "config(base-files)" [label="= 3.0.14-r89.49"]
* Remove the trailing semicolon that was added to each line. It fills
  no purpose.
