[PATCHv4] Script helps add a new patch to the tree.

[Miguel A. Flores Silverio]

It enables the builid macro and uses the name of the patch as
label instead of rpmdev-bumpspec.

* PATCHv2
  - Fix: Fail adding a patch with no description
  - Fix: Fail to add a patch outside the tree
  - Fix: Fail when adding a patch already in the tree directory
  - Fix: Fail to add to git when running script outside tree
  - enables the buildid and changes it to the patch name being added
* PATCHv3
  - replaces "-" [dash] with "_"[uder score] to use patch name
    as builid
* PATCHv4
  - changed mv for cp
  - Fix: conflicts when applying to rawhide
