all: remove dependency on gce repository

Since around 13 December 2025, the gce repository return an error 403,

  error: failed retrieving file 'gce.db' from storage.googleapis.com
   : The requested URL returned error: 403

We then build google-compute-engine and google-guest-agent and host it
under build.kilabit.info repository using the latest releases [1][2].

For google-compute-engine we use version 20251014.00-1.
For google-guest-agent we use version 20251223.00-1.

+#   - pacman will search repositories in the order defined here
+#   - local/custom mirrors can be added here or in separate files
+#   - repositories listed first will take precedence when packages
+#     have identical names, regardless of version number
+#   - URLs will have $repo replaced by the name of the current repo
+#   - URLs will have $arch replaced by the name of the architecture
+#
+# Repository entries are of the format:
+#       [repo-name]
+#       Server = ServerName
+#       Include = IncludePath
+#
+# The header [repo-name] is crucial - it must be present and
+# uncommented to enable the repo.
+#
+
+# The testing repositories are disabled by default. To enable, uncomment the
+# repo name header and Include lines. You can add preferred servers immediately
+# after the header, and they will be used before the default mirrors.
