[PATCH 03/25] CI: remove more dead Travis CI support

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Remove code that I missed in 4a6e4b96026 (CI: remove Travis CI
support, 2021-11-23). This code was only called from or used by the
now-removed .travis.yml, or needed by the Travis CI environment.

For the symlinking in ci/run-build-and-tests.sh: Back when
3c93b829205 (travis-ci: build Git during the 'script' phase,
2018-01-08) and 4b060a4d973 (ci: use a junction on Windows instead of
a symlink, 2019-01-27) adjusted this "ln" command, the Windows build
would use ci/run-build-and-tests.sh.

As seen in 889cacb6897 (ci: configure GitHub Actions for CI/PR,
2020-04-11) the current windows build uses a different entry point
under the GitHub CI, which doesn't use this .prove caching. Namely
"ci/run-test-slice.sh".

We can be certain that it's never used in "ci/run-test-slice.sh"
because to have a ".prove" file we'd need to use "--state=save", which
we only do in the dead Azure codepath in ci/lib.sh. If it were used it
would do the wrong thing, because the different test slices would each
try to clobber the same "t/.prove" file.

If a subsequent run then used the -"-state=failed,slow,save" it would
defeat the purpose of "ci/run-test-slice.sh", since all slices would
then run all tests. I.e. behavior of prove's "--state" options is to
select tests to run from the provided "--state" file, in addition to
those specified on the command-line.

For ci/run-docker{,-build}.sh: It was likewise last referenced in the
.travis.yml removed in my 4a6e4b96026. The current "dockerized" run in
".github/workflows/main.yml" calls the same entry points as the main
"regular" job.
