tectonic-0.15.0-bp160.1.16

-  Update vendored deps. This still won't resolve boo#1230089 as dependencies are
  hard dependencies so they won't be version bumped that easily.

- Fix leap builds

- Replace 0001-build-set-standard-to-c-17.patch to 0001-build-set-c-standard-to-c-17.patch
- Adjust patches for the release branch. tectonic uses a separate branch for releases
  so that's why the patches are failing

- Update vendored dependencies.
- Apply the following patches for icu 75 support
  * 0001-build-set-standard-to-c-17.patch
  * 0002-fix-update-symbols-tags_from_lang-hb_ot_tag_from_lan.patch
- Update _service file and replace obsoleted "disabled" option

- Remove redundant %{cargo_build}

- Update to version 0.15.0
  * The --web-bundle flag can now be used in more situations, specifically
    tectonic -X new and tectonic -X init
  * As part of the above work, you can now activate the "V2" interface with the
  - X flag in more places on the Tectonic command line.
  * The Tectonic.toml file used by the "V2" interface now supports a
    [metadata] section for arbitrary structured user metadata.
  * The "V2" interface also now supports external commands.
    If you have a program named tectonic-blah in your search path, running
    tectonic -X blah will execute it.
  * Running tectonic -Z help (as opposed to tectonic -Zhelp) now actuallyworks
    works

- Update to version 0.14.1
  * Bugfix release
- Update to version 0.14.0
  * Tectonic’s BibTeX engine has been partially translated from C to Rust

  * Update the version of the vendored Harfbuzz library to the latest, 7.3.0
    and all other cargo dependencies.

- Update to version 0.13.0
  * Add new V2 command `tectonic -X init`. This initializes a new document in
    the current directory much like `cargo init`.
  * Setting the `shell-escape-cwd` unstable option.
  * Update many developer dependencies to newer versions
