deb rpm: fix local dependency gem

[kenhys]

Before:

• missing fluent-plugin was installed

After:

• missing fluent-plugin was installed
• missing dependency gem was also installed

NOTE:

• if missing gem requires development packages to build it, it will
  fail.
• fluent-diagtool depends on highly systemd service, so it is simple
  just to use fluent-gem detecting missing gems.

service restart may need some more tweaks in rpm CI, but it is out of this PR.

Let's cache v6 dummy
(We need to remove existing cache once though)

      - name: cache deb
        uses: actions/cache@v4
        id: cache-deb
        with:
          path: |
            fluent-package/apt/repositories
            fluent-apt-source/apt/repositories
            fluent-lts-apt-source/apt/repositories
+            v6-test/fluent-package/apt/repositories
          key: ${{ runner.os }}-cache-${{ matrix.rake-job }}-${{ hashFiles('**/config.rb', '**/Rakefile', '**/Gemfile*', 'fluent-package/templates/**', 'fluent-package/debian/**', 'fluent-package/apt/**/Dockerfile') }}
      - name: Build deb with Docker
        if: ${{ ! steps.cache-deb.outputs.cache-hit }}
        run: |
          rake apt:build APT_TARGETS=${{ matrix.rake-job }}
      - uses: actions/checkout@master
+        if: ${{ ! steps.cache-deb.outputs.cache-hit }}
        with:
          path: v6-test
      - name: Build v6 deb with Docker
+        if: ${{ ! steps.cache-deb.outputs.cache-hit }}
        run: |
          cd v6-test
          git config user.email "fluentd@googlegroups.com"
          git config user.name "Fluentd developers"
          git am fluent-package/bump-version-v6.patch
          rake apt:build APT_TARGETS=${{ matrix.rake-job }}

NOTE:
