Another take to use arch when selecting repo for build target

[abitrolly]

This is another attempt to solve problem that osc build selects OpenSuse_Tumbleweed even if this selection doesn't fit the required architecture.

#241 (comment)

• trace the role of no_repo
• trace the role of repo_names
• check offline logic is not broken (check that offline still
  needed a non-empty repo list before this change)

r.arch == arg_arch looks fishy, shouldn't there be a list somewhere?

[abitrolly]

It is a string comparison of arch that osc repos gives.

[hramrach]

So it returns the same repo multiple times with different arch

[hramrach]

Does not work for me:

localhost:~/home:michals/vertest # osc -d build
hostarch: armv7l
arg_arch: armv7l
arg_repository: None
arg_descr: None
no configured repos for arch armv7l

[abitrolly]

That was a mistake indeed. Fixed that part.

[hramrach]

Looks like this works, thanks

osc -d build
hostarch: armv7l
arg_arch: armv7l
arg_repository: None
arg_descr: None
Building vertest.spec for openSUSE_Leap_15.2_Ports/armv7l

This pull request has been in a draft state for quite some time.
Could you either finish it, close it or add a comment that you're still planning to work on it?

[abitrolly]

@dmach it looks like this PR improves error messages, but I don't remember what I was trying to do and if it reaches that point. Feel free to close it if it has no value.
