Put eopkg files in local repository if available

[jepotter1-archive]

It would make writing packages easier if there was an option to have solbuild put the generated eopkg files into /var/lib/solbuild/local instead of the current directory.

This would help:

• Avoid accidentally checking eopkg files into git
• Make it easier to test packages using the local repository (skip having to copy the eopkg file over to /var/lib/solbuild/local)

Maybe implement a -o option to specify the output location?

Avoid accidentally checking eopkg files into git

This is the wrong way of solving this. Use a global .gitignore to ignore the files.

Make it easier to test packages using the local repository

This is something you can do already with something as simple as an alias, it's what I do.
