Fix rust-latest pipeline job failure due to uninlined-format-args errors from clippy 1.67

Background

• The rust-latest pipeline job started failing in the pipeline as follows (below is from https://gitlab.com/YottaDB/Lang/YDBRust/-/jobs/3669536209).

  error: variables can be used directly in the `format!` string
    --> build.rs:28:5
     |
  28 |     println!("cargo:rust-link-search={}", library_path);
     |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

     = note: `-D clippy::uninlined-format-args` implied by `-D clippy::all`
  help: change this to
     |
  28 -     println!("cargo:rust-link-search={}", library_path);
  28 +     println!("cargo:rust-link-search={library_path}");
     |
  error: could not compile `yottadb` due to previous error

Issue

• clippy 1.67 was released on Jan 26, 2023.

• https://github.com/rust-lang/rust-clippy/blob/master/CHANGELOG.md#rust-167 says the following.

  Moved uninlined_format_args to style (Now warn-by-default) #9865

• Because of this, pre-existing code in build.rs started being called out by clippy for an error from clippy 1.67 (which gets used only in the rust-latest pipeline job) onwards.

Fix

• I originally tried to go with what it suggested. That is, made the following change to build.rs.

  -     println!("cargo:rust-link-search={}", library_path);
  +     println!("cargo:rust-link-search={library_path}");

• But the rust-compat pipeline job started failing with the following error.

  error: there is no argument named `library_path`
    --> build.rs:28:38
     |
  28 |     println!("cargo:rust-link-search={library_path}");
     |                                      ^^^^^^^^^^^^^^

  This job runs with rust 1.47.

• I was not sure how else to fix it so rust 1.47 and rust 1.67 will both be fine with it.

• Therefore, decided to allow uninlined_format_args to not be warned by default. The changes are in .gitlab-ci.yml in the rust-latest job to add a --allow clippy:uninlined-format-args as part of the cargo clippy command.
