- Fix rpmlint complains (removing rubygem-rubyzip.rpmlintrc)

- New upstream release 2.2.0
- Add support for decompression plugin gems #427

- New upstream release 2.1.0
- Fix (at least partially) the `restore_times` and `restore_permissions`
options to `Zip::File.new`
[#413](https://github.com/rubyzip/rubyzip/pull/413)
- Previously, neither option did anything, regardless of what it was set
to. We have therefore defaulted them to `false` to preserve the current
behavior, for the time being. If you have explicitly set either to
`true`, it will now have an effect.
- Fix handling of UniversalTime (`mtime`, `atime`, `ctime`)
fields. [#421](https://github.com/rubyzip/rubyzip/pull/421)
- Previously, `Zip::File` did not pass the options to `Zip::Entry` in some
cases. [#423](https://github.com/rubyzip/rubyzip/pull/423)
- Note that `restore_times` in this release does nothing on Windows and
only restores `mtime`, not `atime` or `ctime`.
- Allow `Zip::File.open` to take an options hash like `Zip::File.new`
[#418](https://github.com/rubyzip/rubyzip/pull/418)
- Always print warnings with `warn`, instead of a mix of `puts` and `warn`
[#416](https://github.com/rubyzip/rubyzip/pull/416)
- Create temporary files in the system temporary directory instead of the
directory of the zip file
[#411](https://github.com/rubyzip/rubyzip/pull/411)
- Drop unused `tmpdir` requirement
[#411](https://github.com/rubyzip/rubyzip/pull/411)
