- Packaging improvements:
* _service change disabled to manual per osc deprecation warning:
WARNING: Command 'disabledrun/dr' is obsolete, please convert
your _service to use 'manual' and then 'manualrun/mr' instead.
* _service change tar and recompress from buildtime to manual
* Update to BuildRequires: golang(API) >= 1.18 matching go.mod
* Drop BuildRequires: fdupes and usage during install step. Go
application packages have a small number of installed files and
this hasn't been an issue following the transition from GOPATH
(where sources were installed) to Go modules where only
binaries and supporting files e.g. doc, license are installed.
* Use %%name macro where applicable to normalize common lines
across Go app packages. Also makes renaming binary easier when
required to handle package name conflict.
