Fix for failure to build from source (FTBFS)

Hello,

I would attach a patch to fix failure to build from source (FTBFS) on rawhide.

Let me explain detail.

1. Below commands are used in the test files.
  Maybe those commands was removed from build root at past time.
  So, need to install those commands manually.

+BuildRequires: %{_bindir}/ps
+BuildRequires: %{_bindir}/hostname


2. I removed below line that is error for rpmlint check.
-Provides: rubygem(%{gem_name}) = %{version}

3. gemspec file's content by created by "gem spec" was changed from Ruby 2.3.?.
-sed -i 's|"Rakefile",||g' %{gem_name}.gemspec
+sed -i 's|"Rakefile".freeze,||g' %{gem_name}.gemspec


I checked below things.
- License check: ok
- rpmlint check: ok
- Install check: ok
- IRB check on mock shell: 
irb(main):001:0> require 'resque'
=> true

I applied this patch into F28+.

This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Vit, thanks for the patch.
